Abstract

Bridge structure in the USA amounted to 577,000 units and as many as 134,000 units (23% of the total bridge) against damage caused by corrosion. This damage requires repairs at a cost not less than U.S.$ 90.9 billion. This damage is similar to the events in Indonesia. This research was performed by use of the calcium Stearate to neutralize reinforcement corrosion in reinforced concrete. Calcium Stearate will react with the cement hydration reaction during the process underway. The result of this reaction is physically looks like a candle. This compound would cover and fill the capillaries when water evaporates in the fresh concrete. This layer does not absorb and impermeable to water and corrosive compounds. So that these compounds caused corrosion of the reinforcement can not penetrate reinforced concrete. The ultimate goal of using calcium Stearate is to increase the service life of aging structures in corrosive areas such as building docks, bridges andrigid layer on the highway. The results showed that the use of calcium Stearate concrete with fly ash at 0% have a tendency of lowering the rate of corrosion of reinforcement and inhibit corrosion. Calcium Stearate with a dose of 2 kg per m3 of concrete can decrease makrocell value amounting to 67%. While on the concrete with fly ash 40%, the addition of 2 kg of calcium Stearate cause makrocell value decreased by 85%.

Dalam rangka meningkatkan pelayanan bidang kependudukan, kabupaten Purbalingga membangun gedung baru Dinas Kependudukan dan Catatan Sipil. Dengan fungsi sebagai perkantoran, gedung dua lantai ini termasuk bangunan dengan kategori resiko II yang menurut peraturan harus memiliki level kinerja minimal LS (Life Safety) untuk kala ulang gempa 500 tahun. Kajian ini bertujuan untuk menentukan kinerja gedung Dinas Kependudukan dan Catatan Sipil kabupaten Purbalingga. Kajian dilakukan menggunakan analisis pushover yang merupakan teknik yang populer oleh karena kemudahaanya, yang banyak digunakan untuk mengevaluasi baik bangunan baru maupun lama. Hasil kajian menunjukkan pada saat tercapai titik kinerja, diperoleh gaya geser dasar sebesar 609510,9 kg dan 687598,1 kg masing-masing pada sumbu X dan sumbu Y. Rasio simpangan yang terjadi masing-masing adalah 0,71% pada sumbu X dan 0,85% pada sumbu Y. Nilai keduanya kurang dari 1% yang menandakan bahwa kinerja struktur gedung Dinas Kependudukan dan Catatan Sipil kabupaten Purbalingga ini berada pada level IO (Immediate Occupancy) dimana tidak terdapat kerusakan yang berarti pada struktur, kekuatan dan kekakuannya kira-kira hampir sama dengan kondisi sebelum gempa. Komponen nonstruktur masih berada ditempatnya dan sebagian besar masih berfungsi jika utilitasnya tersedia. Gedung dapat tetap berfungsi dan tidak terganggu dengan masalah perbaikan. Dapat disimpulkan bahwa perancangan gedung Dinas Kependudukan dan Catatan Sipil kabupaten Purbalingga telah memenuhi kaidah kegempaan

Abstract

The loss due to collapsing structure includes not only materialsbutalso take lives. In thecase of structure function changing that may cause increasing loads, it is required to put efforts instrengtheningthe structure elements in order to increase the capacity and hence to avoid the possibility of collapsing. The objective of this research was to study thebehavior of T-sectional reinforced concrete beamstrengthenedin the negative momentregionwithwire rope and mortar composite. The test was carried out to three T-sectional beams: without wire rope reinforcement (BK), with 2 wire rope reinforcements (BP1), and with 4 wirerope (BP2) reinforcements. The type of wire rope was Independent Wire Rope Core (IWRC) with10 mm diameter. The testing method used was two points static loading with flens positions below (the flens part experienced tensile stress). Results showed that the maximum load carryingcapacity of BP1 and BP2 specimens increased by ratios of 1.59 and 2.03 to the BK specimen respectively. However, the increase was achievedafter the development and propagation of highcracking. Ductility of BP1 and BP2 specimens decreased by ratios of 0.62 and 0.36 to the BK specimen respectively. The initial stiffness of BP1 and BP2 increased byratios of 1.09 and 1.08 to the BK specimen respectively.The effective stiffness ofBP1 and BP2 specimensdecreased by ratios of 0.88 and 0.92 to the BK specimenrespectively. Stress occurred in the wire rope based on the analysis results of Response-2000 and the layer method have not reached 50% ofthe ultimate stress resulted from the preliminary test. In general, unless improvement was given to the stiffness characteristics of thewire rope, its contribution would not become optimum.

Abstract

Indonesia menempati posisi ketiga dunia dari 153 negara yang memiliki potensi bahaya gempa. Hal ini disebabkan Indonesia merupakan tempat bertemunya tiga lempeng besar dunia yaitu Lempeng Indo-Australia, Lempeng Eurasia, dan Lempeng Pasifik. Interaksi antara ketiga lempeng inilah yang menyebabkan Indonesia memiliki aktivitas kegunungapian dan kegempaan yang tinggi. Perubahan peraturan gempa Indonesia berpeluang menyebabkan terjadinya perubahan kinerja struktur gedung. Makalah ini bertujuan untuk mengkaji kinerja model struktur gedung lima lantai pada kondisi tanah keras di wilayah Banyumas akibat beban gempa SNI 03-1726-2002 dan SNI 03-1726-2012, yang dilakukan dengan analisis beban dorong (pushover). Hasil kajian menunjukkan bahwa terjadi peningkatan gaya geser dasar sebesar 1,48% pada model struktur gedung saat tercapai titik kinerja (performance point). Displacement yang terjadi mengalami peningkatan sebesar 19,61% sedangkan daktilitas mengalami penurunan sebesar 43,14%. Kinerja model struktur gedung tidak mengalami perubahan yaitu tetap pada level Immediate Occupancy dimana tidak terdapat kerusakan yang berarti pada struktur, kekuatan dan kekakuannya kira-kira hampir sama dengan kondisi sebelum gempa. Komponen nonstruktur masih berada ditempatnya dan sebagian besar masih berfungsi jika utilitasnya tersedia. Gedung dapat tetap berfungsi dan tidak terganggu dengan masalah perbaikan.
