Abstract

Undang-Undang Nomor 38 Tahun 2004 tentang Jalan dan Undang-Undang Nomor 22 Tahun 2009 tentang Lalu lintas dan Angkutan Jalan mengamanatkan bahwa pengoperasian jalan umum dilakukan setelah dinyatakan memenuhi persyaratan laik fungsi secara teknis dan administrasi oleh Penyelenggara Jalan. Tujuan dari pelaksanaan penilaian kelaikan fungsi jalan adalah untuk memastikan bahwa jalan tersebut sesuai dengan standar kelaikan sehingga berkeselamatan bagi semua pengguna jalan. Jembatan sebagai bagian jalan mempunyai peranan cukup penting dalam menjaga ketersambungan antar jaringan jalan.  Akan tetapi, belum adanya parameter yang jelas dalam penilaian kelayakan struktur jembatan sebagai syarat penerimaan uji laik fungsi jalan menjadi suatu kendala. Pengujian jembatan dengan cara uji beban statik membutuhkan usaha yang cukup besar, baik secara biaya, waktu serta resiko terhadap struktur itu sendiri. Metode pengujian lain yang cukup efektif dan handal adalah dengan uji getar, dimana dapat secara langsung menggambarkan respons dan perilaku aktual dari struktur yang kemudian dibandingkan dengan perilaku struktur berdasarkan permodelan. Jembatan Kalikuto terletak pada ruas tol Semarang – Batang, Jawa Tengah merupakan bagian dari Jalan Tol Trans Jawa dengan bangunan atas berupa steel box arch bridge, memiliki bentang 100 meter dan lebar 32 meter. Sebelum dibuka untuk lalu lintas umum pada Desember 2018, telah dilakukan rangkaian pengujian unruk menilai kelaikan dari jembatan. Hasil uji getar diperoleh nilai frekuensi alami vertikal sebesar 1.251 Hz, dimana nilainya masih di atas nilai frekuensi pemodelan / teoritis sebesar 1.049 Hz, serta rasio redaman jembatan sebesar 2.10% - 3.88%. Hal ini menunjukkan bahwa Jembatan Kalikuto layak secara keberfungsiannya dan handal secara struktur.

Abstract

Studi ini membahas prosedur perhitungan gaya tarik awal kabel pada jembatan beruji kabel melalui pendekatan balok bentang jamak. Metode ini dipilih karena menawarkan kemudahan dan kecepatan dalam perhitungan tanpa harus melakukan proses iterasi. Selain itu, perhitungan dengan metode ini memberikan hasil distribusi gaya tarik kabel yang rasional dan memenuhi persyaratan perancangan jembatan beruji kabel. Keuntungan lain adalah metode ini tidak tergantung pada fitur perangkat lunak yang digunakan sehingga memudahkan bagi para perencana untuk dapat lebih leluasa melakukan optimasi terhadap model struktur jembatan beruji kabel. Perbandingan  dua model jembatan beruji kabel dengan geometri simetris dan asimetris dilakukan untuk memverifikasi perhitungan. Berdasarkan perbandingan tersebut, metode pendekatan balok bentang jamak dapat memberikan besaran momen lentur pada dek jembatan dan deformasi lateral pada pylon yang lebih kecil dibandingkan dengan prosedur yang digunakan dalam literatur. Distribusi gaya penarikan awal kabel akibat beban mati yang bekerja dengan menggunakan pendekatan balok bentang jamak menunjukkan perilaku yang rasional dan dapat merepresentasikan efektifitas daya dukung ruji kabel sebagai fungsi dari nilai sudut antara ruji kabel dan dek jembatan. Hal ini ditunjukkan dengan nilai gaya tarik kabel yang semakin besar apabila posisi titik tumpu semakin menjauhi pylon.

Abstract

AbstractThe construction of bridge is often constrained by environmental factors, one of which is flooding. Kaligawe Bridge is located across the Banjir Kanal Timur (BKT) of Semarang City. In December 2018 to March 2019 there was an increase in rainfall which resulted in flooding at BKT which delayed the work of bridge construction. The demolition work on the existing pillars began in December 2018 and is targeted to be completed in February 2019 due to flooding. In addition, the actual depth of the original design pillar is -3.50 meters in the field became -8.00 meters below normal water level, so that the demolition can only be completed on May 31, 2019. From the 3 month delay, the remaining time for completion of 2 bridges until the end of December 2019 is only 7 months left. Therefore, an acceleration strategy is needed to meet the completion target. One strategy is to accelerate the concrete curing time for pillar and floor by increasing the the designed concrete strength fc’ = 30 MPa to strength fc’ = 35 MPa. Thus, the curing time of concrete pillars and decks that were originally 21-28 days theoretically could be accelerated to less than 7 days. The use of higher concrete strength as a step to accelerate the concrete curing time is considered effective, with the potential for cost optimization of 2.90% of the contract value. Key words: higher concrete strength, curing time, concrete, bridge ­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­AbstrakPelaksanaan pekerjaan jembatan seringkali terkendala oleh faktor lingkungan, dimana salah satu diantaranya adalah banjir. Jembatan Kaligawe terletak melintas di atas Banjir Kanal Timur (BKT), Kota Semarang. Pada bulan Desember 2018 hingga Maret 2019 terjadi kenaikan intensitas hujan sehingga mengakibatkan banjir kiriman di BKT yang menghambat pelaksanaan pekerjaan. Pekerjaan pembongkaran pilar eksisting mulai dilaksanakan bulan Desember 2018 dan ditargetkan selesai bulan Februari 2019 terkendala akibat banjir. Selain itu, kedalaman eksisting pilar rencana semula -3.50 meter aktual di lapangan menjadi -8.00 meter di bawah muka air normal, sehingga pembongkaran baru dapat diselesaikan pada 31 Mei 2019. Dari keterlambatan 3 bulan tersebut, maka sisa waktu untuk penyelesaian untuk 2 buah jembatan sampai akhir Desember 2019 tinggal tersisa 7 bulan. Oleh karena itu, diperlukan strategi percepatan untuk dapat memenuhi target penyelesaian. Salah satu strategi yaitu percepatan waktu tunggu umur beton pilar dan plat lantai dengan menaikkan mutu beton rencana fc’ = 30 Mpa menjadi mutu beton fc’ = 35 Mpa. Dengan demikian, waktu tunggu umur beton pilar dan plat lantai yang semula 21-28 hari secara teori dapat dipercepat kurang dari 7 hari. Penggunaan mutu beton lebih tinggi sebagai langkah percepatan waktu tunggu umur beton dirasa efektif, dengan potensi optimasi biaya sebesar 2,90 % terhadap nilai kontrak. Kata kunci: mutu beton lebih tinggi, waktu tunggu, beton, jembatan

Abstract

The use of precast technology in the manufacture of segmental components for the bridge substructure is one application that can be used in the acceleration of bridge construction. Better concrete quality and precision are two advantages that can make precast technology a solution in accelerating bridge construction. Commonly, segmental precast concrete piers are not designed to resist earthquake loads; however, the use of segmental piers systems is still possible in seismic zones by limiting additional dead loads. This study discusses the load limitation using the dynamic response calculation methodology of segmental precast concrete pillar structures to the El Centro (1940) earthquake load by varying the slenderness of the piers/column between 22 to 100. Examination of the stress combination due to axial load (DL) and inertia load due to the earthquake is carried out to find out how much residual stress can be accommodated by the piers/columns. Additional dead load (WADD) is obtained by using Newton's second law by dividing the allowable additional inertial load based on the residual stress to the peak ground acceleration. The calculation results show a good correlation between piers’/columns’ slenderness and the proportion of additional dead load (WADD) to dead load (WDL), so that the applicability of using segmental precast concrete piers/columns in seismic zones can be predicted earlier through this correlation.

Abstract

The elevated road construction which is originally intended to overcome congestion at the intersection of the highway/train, actually sometimes worsen the congestion that exists during the construction period. Therefore, a new construction method and technology is needed to minimize the congestion and provide a short construction period. CSS-Mortar Foam is a new technology introduced by the Research Center of the Ministry of PUPR (Pusjatan) in 2016 which has been applied to the construction of the Antapani flyover in Bandung. A study is needed to compare the construction cost of this technology with the technology of the overpass structure which is commonly used, namely PCI-Girder. Data collection process in this study are planning and DED data, inventory of work items and volumes, and the unit price. The next step is the construction-costs calculation process of the proposed alternative-construction types. The calculation of construction costs was carried out using the Work Unit Price Analysis (AHSP) which is developed by the Directorate General of Highways based on the third revision of 2010 General Specifications. The results showed that the alternative CSS-Mortar Foam construction types was able to reduce the construction costs of flyovers by 44.7% compared to the PCI-Girder construction type. Thus, CSS-Mortar Foam construction can be used as a more efficient alternative for flyovers/bridges construction.

Abstract

Kabel merupakan salah satu elemen utama pada jembatan cable stayed yang fungsinya memikul dan meneruskan beban pada balok dan lantai jembatan ke struktur pilon. Elemen kabel perlu selalu dilakukan monitoring dan pemeliharaan selama umur jembatan, sehingga gaya kabel yang bekerja tidak melampaui kapasitasnya. Salah satu metode dilakukan dengan uji dinamik, dimana nilai parameter dinamik (frekuensi dan mode getar) berkorelasi dengan gaya tarik kabel. Selain parameter dinamik, gaya tarik kabel juga dipengaruhi oleh parameter fisiknya, yaitu parameter tak-berdimensi l2 akibat efek kelengkungan (sag effect) dan parameter tak-berdimensi x akibat efek kekakuan lentur (bending stiffness effect). Berbagai rumusan pendekatan telah dikembangkan oleh para ahli, diantaranya: taut string, beam string, wei-xin, dan zui et.al. theory. Studi ini akan membahas perbandingan rumusan tersebut dengan mengambil studi kasus Jembatan Pedamaran 1, Riau. Hasil studi menunjukkan bahwa parameter tak berdimensi l2 dan x “cukup berpengaruh” dan perlu ditinjau dalam perhitungan, dimana kombinasi dari kedua parameter tersebut memberikan pengaruh sebesar 1.77% - 6.00% terhadap estimasi gaya tarik kabel. Penggunaan rumusan empiris taut string theory dan beam string theory memberikan estimasi gaya tarik kabel dengan tingkat kesalahan di bawah 7,0%, sedangkan rumusan empiris wei-xin dan zui et.al. memberikan hasil dengan akurasi paling baik dengan kesalahan di bawah 3,0%

Abstract

Soil condition in the construction of the Semarang-Demak II Toll Road Project on the northern coast of Java Island is dominated by soft soil. Soft soil has the potential to cause problems such as relatively low permeability, poor bearing capacity, and large long-term settlements that will cause damage to the construction above it in the future. Therefore, it is necessary to improve the soft soil capacity, one of which is the Preloading and PVD-PHD combination method. This study aims to evaluate the value of settlement and consolidation time of embankment on soft soil between design and construction. The research method is carried out by field investigation/survey methods to obtain data on the settlement magnitude and consolidation time of embankment, and find possible causes of differences. The study found that there were differences in the value of the settlement and the consolidation time between the design and actual conditions in the field. The final settlement when the degree of consolidation reached 90% was observed to be almost the same between the design and actual condition, where the difference was 0.0063 meters or 2.81%. However, a significant difference was found between the time of consolidation for design and construction, which was 28 days (14.70%) faster than the estimation time. Factors that influence the difference in consolidation time, include: the volume weight of the preloading embankment in the field is 1.65 kN/m3 (9.70%) higher than the plan, the embankment elevation in the field is 0.237 meters (3.36%) higher than the design, and the use of drainage well to dissipate water trapped in the “trap-zone” in the middle of the embankment.

Abstract

The population of bridges on National Road in 2020 has reached 21,054 units with a total length of 587,309 meters. About 10.5% of bridges have a service life of less than 10 years, 68.1% in the range of 10 - 50 years, and 5.3% more than 50 years. As the service life increases, the condition of the bridge will decrease. This bridge condition is obtained from the results of a detailed inspection using the visual method. The accuracy of this method is highly dependent on the objectivity, ability, and experience of the bridge inspector. The large population of bridges, variations in service life and conditions, and limited experienced inspectors are obstacles in conventional bridge inspections. As an alternative, the dynamic test method can be used to check bridge conditions more quickly and accurately. The natural frequency of the dynamic test can be used to determine the integrity condition and the level of structural damage, by comparing it to the theoretical frequency. So far, the theoretical frequency is determined based on calculations or structural modeling. The limited data of technical specifications, design drawings, and as-built drawings are often an obstacle. Experience and special skills are also needed in calculating or modeling this structure. This study aims to analyze the correlation between frequency and bridge span based on bridge dynamic test data in Indonesia. The results obtained a mathematical formula, where the value of the frequency of the bridge is correlated to the span of the bridge with a correlation coefficient of -0.85. This coefficient shows that the relationship between the variables under consideration is very strong and inverse, where the longer the bridge span, the smaller the vertical frequency value of the bridge.

Abstract

The demand for an acceleration of project completion time is often an obstacle, especially in structural work which is a critical path. The length of time for concrete curing and formwork dismantling sometimes obstructs the progress of the project. The time required for casting, concrete curing and unloading of formwork in a long span bridge construction project is ± 14 days with a record that there are no obstacles in the field. Based on these problems, researchers are trying to provide an alternative solution through a compressive strength test with a variant of the concrete quality and the curing time using chemical additives type F and type D. The study aims to find the minimum concrete compressive strength, the curing time, and the effects of adding a chemical additive that refers to General Specifications Standard 2018 (70% of the designed concrete compressive strength). The variant of the concrete quality is 40 MPa, 50 Mpa, and 60 Mpa while the variant of the curing time is 1,2,3,7, and 28 days. Based on the study, the minimum concrete compressive strength for each concrete quality is 28,58 MPa, 36,85 MPa, and 46,25 MPa. The curing time needed for fc’ 40 MPa and fc’ 50 Mpa is 2 days while for fc’ 60 MPa is 3 days. The use of chemical additives also has an impact on increasing compressive strength. The maximum compressive strength value of 28 days is found in the variation of f'c 60 Mpa of 62.20 Mpa with additive content of type F dan D of 0.6% and 0,15% of the cement weight. Optimum compressive strength is achieved when the curing process is done using the soaking method. Key words: critical path, formwork, chemical additives, compressive strength, soaking method.

Abstract

Pembangunan jembatan dengan konsep “accelerated bridge construction” telah banyak dikembangkan sejak tahun 2015. Infrastruktur jembatan yang dapat dibangun dalam waktu singkat menjadi harapan bagi semua stakeholder, terutama pengguna lalu lintas, di mana ketersediaan aksesibilitas dan konektivitas melalui pembangunan jembatan segera dapat terpenuhi. Kemungkinan ini dapat diwujudkan dengan adanya kemajuan dan inovasi teknologi jalan-jembatan, serta adanya penemuan material-material baru. Salah satu inovasi yang dapat mendukung percepatan pembangunan jembatan tersebut adalah penggunaan sistem steel box telescopic sebagai kepala pilar jembatan menggantikan sistem konvensional yang umumnya menggunakan teknologi beton cast in situ. Dalam kajian digunakan model numerik dari sistem steel box telescopic pada 50-55 meter jembatan tipe I-girder untuk meninjau aspek kelayakan teknisnya. Berdasarkan tinjauan pada aspek teknis, penggunaan sistem steel box telescopic ini dapat mereduksi berat kepala pilar secara signifikan dibandingkan dengan sistem konvensional. Hal ini tentu saja dapat mereduksi dimensi pilar sebagai akibat dari berkurangnya berat kepala pilar, terutama akibat beban gempa. Tinjauan lebih lanjut diperlukan terkait aspek detailing dan kelayakan secara ekonomi sistem steel box telescopic dibandingkan sistem konvensionalKata kunci: accelerated bridge construction, steel box telescopic, kepala pilar
