<![CDATA[Abstract. One of the important requirements for earthquake resistant building related to confinement is the use of seismic hooks in the hoop or confining reinforcement of reinforced-concrete column elements. However, installation of a confining reinforcement with a 135-degree hook is not easy. Therefore, in practice, many construction workers apply a confining reinforcement with a 90-degree hook (non-code compliant). Based on research and records of recent earthquakes in Indonesia, the use of a non-code compliant confining reinforcement for concrete columns produces structures with poor seismic performance. This paper presents a study that introduces an additional element that is expected to improve the effectiveness of concrete columns confined with a non-code compliant confining reinforcement. The additional element, named a pen-binder, is  used to keep the non-code compliant confining reinforcement in place. The effectiveness of this element under pure axial concentric loading was investigatedcomprehensively.The specimens tested in this study were 18 concrete columns,with a cross-section of 170 mm x 170 mm and a height of 480 mm. The main test variables were the material type of the pen-binder, the angle of the hook, and the confining reinforcement configuration.The test results indicate that adding pen -binders can effectively improve the strength and ductility of the column specimens confined with a non-code compliant confining reinforcement. ]]>

<![CDATA[This paper presents results of numerical and experimental study of shear link behavior, utilizing diagonal stiffener on web of steel profile to increase shear link performance in an eccentric braced frame (EBF) of a steel structure system. The specimen is to examine the behavior of shear link by using diagonal stiffener on web part under static monotonic and cyclic load. The cyclic loading pattern conducted in the experiment is adjusted according to AISC loading standards 2005. Analysis was carried out using non-linear finite element method using MSC/NASTRAN software. Link was modeled as CQUAD shell element. Along the boundary of the loading area the nodal are constraint to produce only one direction loading. The length of the link in this analysis is 400mm of the steel profile of WF 200.100. Important parameters considered to effect significantly to the performance of shear link have been analyzed, namely flange and web thicknesses, thickness and length of web stiffener, thickness of diagonal stiffener and geometric of diagonal stiffener. The behavior of shear link with diagonal web stiffener was compared with the behavior of standard link designed based on AISC 2005 criteria. Analysis results show that diagonal web stiffener is capable to increase shear link performance in terms of stiffness, strength and energy dissipation in supporting lateral load. However, differences in displacement ductilityâs between shear links with diagonal stiffener and shear links based on AISC standards have not shown to be significant. Analysis results also show thickness of diagonal stiffener and geometric model of stiffener to have a significant influence on the performance of shear links. To perform validation of the numerical study, the research is followed by experimental work conducted in Structural Mechanic Laboratory Center for Industrial Engineering ITB. The Structures and Mechanics Lab rotary PAU-ITB. The experiments were carried out using three test specimens with model and dimension identical to the model in the numerical study. Experimental testing apparently has shown results of the same behavior as predicted in the numerical study. However, when it is compared to the shape of the hysterical curve, a slight difference is apparent. This is due to the influence of stiffness of bolt joints and the supports which is difficult to model precisely in the numerical studies. ]]>

<![CDATA[Abstrak. Offshore Platform biasanya menggunakan struktur baja tubular sebagai komponen utama penyusunnya. Kerusakan dapat terjadi pada bagian joint tubular, salah satu cara untuk memperbaikinya adalah dengan sistem grouted joint. Sistem grouted joint ini dianggap efektif karena biayanya yang tidak terlalu mahal dibandingkan dengan cara yang lain serta tidak mengganggu kegiatan operasional platform karena pengerjaannya tidak menghasilkan api. Perumusan mengenai kapasitas dari tubular joint (tanpa grout dan dengan grout) sudah dirumuskan di dalam API RP 2A WSD (American Petroleum Institute Recommended Practice 2A Working Stress Design) 2007. Hasil perhitungan manual berdasarkan code API ini akan dicek dan dibandingkan serta dianalisis dengan hasil dari pemodelan elemen hingga. Dari hasil analisis diperoleh kenaikan kapasitas aksial tarik rata-rata yaitu 52,75% (min. -6% dan maks. 116%).Kenaikan kapasitas aksial tekan rata-rata yaitu 343,75% (min. 230% dan maks. 468%). Kenaikan kapasitas momen lentur searah bidang rata-rata yaitu 68,88% (min. 36% dan maks. 98%). Kenaikan kapasitas momen lentur keluar bidang rata-rata yaitu 220,50% (min. 71% dan maks. 577%). Sedangkan perbedaan hasil antara perhitungan manual berdasarkan API dan pemodelan elemen hingga memiliki perbedaan rata-rata sebesar 19% (min. 2% dan maks 42%).Abstract. Offshore platform are usually made of tubular steel as main component. Damage can occur in tubular joint, one way to restore the joint capacity is to apply grouted joint system. Grouted joint system is considered to be the most effective because the cost isnât too expensive compared to the other retrofitting and doesnât disturb the platform operations. Formulation of the capacity of the tubular joint already defined in API RP 2A WSD code (American Petroleum Institute Recommended Practice 2A Working Stress Design) 2007. Manual calculation results will be compared and analyzed with the results from finite element modeling. This research examined the amount of increase in tubular joint capacity of all the loadings. From the analysis shows that the increase in axial tension capacity of the average is 52.75% (min. -6% and max. 116%). The increase the capacity of the average axial compression is 343.75% (min. 230% and max. 468%). The increase in in-plane bending moment capacity of the average is 68.88% (min. 36% and max. 98%). The increase in out-of-plane bending moment capacity of the average is 220.50% (min. 71% and max. 577%). While the difference in results between the manual calculations based on API and finite element modeling have an average difference of 19% (min. 2% and max 42%).]]>

<![CDATA[Abstract. In this study a method to couple the finite element method (FEM) and the boundary element method (BEM) for solving structural analysis problems is investigated and implemented. The investigation is focused on developing and selecting a practical method for integrating the system of linear equations derived from the FEM and the BEM into a combined global system, and to study the efficiency and accuracy of the coupled method. A coupling method that based on transforming the system of equation from the BEM into a form that can be assembled to the global system of equation of the FEM is implemented. The coupled method is useful for solving structural analysis problem of shear wall-frame building. Shear walls are modeled as plane stress BEM regions, while frames are modeled as beam-column FEM regions. The accuracy and efficiency of the coupled method is studied by solving structural analysis problems of an 8 stories shear wall-frame building model. The coupled FEM and BEM method has been implemented for structural analysis of shear wall-frame building in a personal computer program. The coupled method is much more complicated to implement compared to the FEM. However, the benefit of reduced complexity in mesh generation and increased efficiency in both memory requirement and computing time can be very significant.Abstrak. Pada studi ini diteliti metode untuk menggabungkan metode elemen hingga (FEM) dengan metode elemen batas (BEM) dalam menyelesaikan masalah-masalah analisis struktur. Fokus penelitian adalah mengembangkan dan memilih metode yang praktis untuk menggabungkan sistem persamaan linier yang diturunkan dari FEM dan BEM menjadi satu sistem persamaan global, dan untuk mempelajari efisiensi dan akurasi dari metode gabungan. Metode penggabungan yang diterapkan pada dasarnya mentransformasikan sistem persamaan BEM menjadi bentuk yang dapat dirakit ke sistem persamaan global FEM. Sistem gabungan dipergunakan untuk menyelesaikan masalah analisis struktur gedung dengan sistem struktur portal dan dinding geser. Dinding geser dimodelkan dengan BEM plane stress, sedangkan portal dimodelkan dengan FEM balok-kolom. Metode gabungan diterapkan menjadi program komputer. Akurasi dan efisiensi metode gabungan dipelajari dengan menyelesaikan analisis struktur gedung 8 lantai dengan sistem portal-dinding geser. Sistem gabungan lebih rumit dalam proses pemrogramannya, tetapi keuntungan diperoleh dari kemudahan pembuatan model struktur dan peningkatan efisiensi dalam pemakaian memori komputer dan waktu penyelesaian.]]>

<![CDATA[Abstrak. Makalah ini menyajikan hasil studi numerik yang meneliti perilaku link geser dengan menggunakan pengaku diagonal pada bagian badan untuk meningkatkan kinerjanya, pada sistem struktur baja berpengaku eksentrik (EBF). Penelitian ini bertujuan untuk meneliti perilaku link geser dengan menggunakan pengaku diagonal pada bagian badan dibawah pembebanan statik monotonik dan siklik dengan kontrol perpindahan, riwayat pembebanan yang diberikan dalam pengujian ini sesuai dengan standar pembebanan AISC 2005. Analisis dilakukan dengan pendekatan elemen hingga Non-Linier dengan menggunakan perangkat lunak komputer MSC/NASTRAN. Link dimodelkan sebagai elemen shell yang ditumpu pada kedua ujungnya sedangkan beberapa nodal pada posisi pembebanan diperbolehkan untuk bertranslasi dalam satu arah saja (sumbu-y).. Beberapa parameter penting yang dianggap berpengaruh secara signifikan terhadap kinerja link geser telah dianalisa mencakup: tebal sayap, tebal badan, tebal dan jarak pengaku badan, tebal pengaku diagonal dan geometrik pengaku diagonal. Perilaku link geser dengan pengaku diagonal badan dibandingkan dengan perilaku link standar yang direncanakan sesuai dengan ketentuan AISC 2005. Hasil analisis menunjukkan bahwa pengaku diagonal badan dapat meningkatkan kinerja link geser dalam hal: kekuatan kekakuan dan dissipasi energi dalam menahan beban lateral. Namun, perbedaan nilai daktilitas antara link geser dengan pengaku diagonal badan dan link geser yang direncanakan sesuai standar AISC tidak begitu signifikan. Hasil analisis juga menunjukkan bahwa ketebalan pengaku diagonal dan model geometrik pengaku tersebut berpengaruh secara signifikan terhadap kinerja link geser. Abstract. This paper presents a numerical study to investigate the behaviour of shear link in case of enhancement of the shear link performance of Eccentrically Braced Frames (EBF) of steel structures by using diagonal web stiffenner. This research aims to investigate the behaviour of shear link with diagonal stiffenner under monotonic and cyclic of loading with displacement control, the loading hystory is applied to the model of link accordance with standard of AISC 2005. Non-Linier Finite Element Method is applied using the computer software of MSC/NASTRAN. Link is modeled as shell element and fixed at its both ends except for degree of freedom of the vertical displacement (y-direction) at the one end where the load is applied. Several important parameters of shear link has ben investigated: the thickness of flange, web and web stiffener, the space of web stiffner, the thickness of diagonal web stiffner and its geometric. The behaviour of shear link with diagonal web stiffener is compared to the behaviour of the link designed in accordance with the AISC 2005 Standard Code of Practice. The results of the analysis show that the diagonal web stiffener increases the performance of the shear link in terms of strength, stiffness, energy dissipation to resist lateral load. However, the difference between the ductilities of the link with diagonal web stiffenner and standard link of AISC Code is not significant. Parameters which are significantly influencing the performance of the shear link are the thickness of diagonal web stiffener and its geometry.]]>

<![CDATA[Abstrak. Salah satu persyaratan penting untuk konstruksi tahan gempa yang terkait dengan pengekangan adalah pemasangan tulangan pengekang dengan kait gempa 1350 pada sengkang. Dalam pelaksanaannya banyak pelaksana konstruksi menggunakan tulangan pengekang dengan kait 900 atau dengan konfigurasi dobel C (tidak sesuai standar). Berdasarkan beberapa hasil penelitian dan beberapa catatan dari kejadian gempa di Indonesia akhir-akhir ini, pemasangan tulangan pengekang yang tidak sesuai standar untuk kolom beton bertulang menghasilkan kinerja yang buruk sebagai struktur tahan gempa. Makalah ini memaparkan hasil eksperimen yang bertujuan mengembangkan elemen tambahan (pen-binder) untuk meningkatkan efektivitas pengekangan kolom beton dengan tulangan pengekang yang tidak sesuai standar. Efektivitas dari tambahan elemen untuk meningkatkan kinerja pengekangan pada beberapa konfigurasi tulangan pengekang yang tidak standar ini diuji dengan beban aksial dan lateral siklis. Benda uji berjumlah 5 buah kolom, dimensi penampang 260 mm x 260 mm dan tinggi 1500 mm. Variabel pengujian adalah jenis material pen-binder,level beban aksial dan sudut kait yang digunakan dalam tulangan pengekang. Hasil pengujian menunjukkan bahwa modifikasi terhadap tulangan pengekang tidak standar efektif mengekang inti beton, meningkatkan daktilitas dan kemampuan disipasi energikolom benda uji.Abstract. One of the important requirements for earthquake resistant buildings associated with confinement is the use of seismic hook (135-degree hook) in hoop. Therefore, in practice many construction workers use confining reinforcement 90-degree hook or with double C configuration (code non-compliance). Based on some research and some records of recent earthquakes in Indonesia, the use of the code non-compliance confining reinforcement for reinforced concrete columns can result in structures with poor seismic performance. This paper presents the results of experimental study with an objective to develop an additional element (pen-binder) expected to improve the effectiveness of concrete columns confined with non-compliance confining reinforcement. The effectiveness of this additional element in improving the performance of some configuration of non-compliance confining reinforcement in columns under axial and lateral cyclic loading was investigated in this study.The specimens tested in the study were 5 column specimens, with 260 mm x 260 mm in cross section and 1500 mm in height. The test variables were types of pen-binder material, level of axial load, angle of hook applied. The test results indicate that confining reinforcement modification can be effective in confining the core concrete, improving ductility and dissipation energy of column specimens.]]>

<![CDATA[Prestressed concrete has been gaining popularity in the construction industry because of its many advantages, which include reduced dead load due to less material used and overall cost savings. Nonetheless, a single prestressed concrete I-girder as a structural element in highway bridges is still significantly costly and massive, so optimization can yield a significant amount of cost savings as well as reduced material consumption. In this study, prestressed concrete I-girder optimization was carried out by implementing a genetic algorithm (GA), a method inspired by nature’s evolution and natural selection. This study evaluates a number of aspects of applying a genetic algorithm for optimization of material cost of a prestressed concrete I-girder design. A new method for calculating the fitness value is proposed, which was proven to be essential for the application developed in this study. The best solution that resulted from the optimization process is presented, defined by being the least costly solution while still maintaining compliance with the AASHTO LRFD 2007 design code, which includes ultimate strength, service stresses and deflection, detailing requirements, geometrical feasibility, etc. Lastly, a sensitivity analysis was carried out, discussing the influence of the starting conditions on the output of the optimization process.]]>
