"Studying about cable stayed bridge become trend in the last few years. Since the improvement of the material technology and the need of longer bridge so the cable stayed bridge become more important in the last few years.Since the span become longer, so the structure will become more flexible and external load such are traffic, wind, rain and earthquake become more significant to the structure. When the displacement of the deck will increase, it will make uncomforting for human. Many scientists and engineers try to make a control of cable stayed bridge, so that the response will become safety and good for human comfort also.In this study we try to simulate the model from experiment to the behavior of the cable stayed bridge itself. We also try to control the response of the structure. This control that we have done must be realistic and easy to use.In fact with computer simulation we can do such sophisticated control, but the main problem if it's not applicable the control that we use become useless, otherwise it will be dangerous also if we get a result in reality far from out simulation.So in this study we do simple control to cable stayed bridge, and do some test that could be realistic in the reality. The sag of the cable is big and it will make a non linear effect. We do some analysis of cable stayed bridge in ANSYS 5.5.3 and do control simulation in SIMULINK by catching the static non linear result from ANSYS 5.5.3.The simulation that we done here to see the effectives of the control in many cases. We can be sure that the control is good if we get a good solution with the control of the structure."

"In the framework of the design of Cisadane Cable Stayed Bridge, a wind tunnel testing on scaled model has been conducted lo observe its aerodynamic forces. The wind tunnel which is used for test, was a low speed wind tunnel.The test results are the coefficient Ci, Cd and Cm. The coefficients can be used lo calculate the load of the structure, the lift Force and the pitching moment. Based on the test results, shape improvement of the proposed bridge deck is also considered."

"ABSTRACTThe present study deals with the static and dynamic behavior of cable-systems and cable-stayed bridge systems. In the static analysis, linear. and geometry nonlinearities such as large-deflections and stress-stiffening are evaluated. In the dynamic analysis, only linear: analysis is taken into account, the nonlinearities are disregarded. In the cable system, there are two cable models evaluated, i.e., the horizontal cable-systems and inclined cable-systems. The cable systems are modeled as three-dimensional (3-D) structural system. The various prestressed forces in the cables are investigated, and the results show that the nonlinearity effects do not quite have an influence when the prestressed forces are between 21% - 45% fp. and 15% - 45% fpU for the horizontal cable and inclined cable-systems, respectively. The transverse (coupling effect) stiffnesses are nearly zero for the prestressed forces in the cable between 16% - 45% Cu. The dynamic characteristic of both cable-systems are quite similar, with the first mode is out-of-plane motion. The gravity acceleration does not take an important influence in the dynamic behavior of the cable-systems study herein. In the cable-stayed bridge systems, two common types of cable-stayed bridge are investigated, namely the fan-type and the harp-type cable-stayed bridge. The bridges are modeled as two-dimensional (2-D) structural system. The comparison results of axial forces in the cables, vertical displacement in the mid-point of middle span, horizontal displacement at top of pylon, bending moment in the deck, axial forces in the deck and also vertical reaction at foundation of pylon are all investigated. The results show that the nonlinearity effects with the prestressed forces in stay cable between 16% - 45% fp? seem do not have quite important influence. The natural frequencies and mode shapes for the first 20 modes are presented and the results are quite similar for the both bridge systems. The influence of dead load multiplier to the dynamic characteristic of such bridges are also evaluated and the results show that the structure buckle under 19 DL (Dead Load) and 15 DL for the fan and harp-type, respectively. These results show that bridge models studied herein are in the safe design consideration."

"Tahapan konstruksi ketika pembangunan jembatan cable-stayed akan berpengaruh terhadap analisis strukturnya. Respon struktur yang dihasilkan ketika analisis dilakukan secara langsung (jembatan utuh) tanpa memperhitungkan tahapan konsturksi akan berbeda dengan analisis sequential sesuai dengan tahapan konstruksinya.Tulisan ini akan membandingkan hal tersebut. Untuk itu, analisis sequential perlu dilakukan sesuai tahapan konstruksi yang dilakukan. Gaya kabel prategang yang diberikan akan berbeda antara analisis langsung dengan analisis sequential. Gaya tersebut tergantung boundary condition yang ingin dicapai. Gaya dalam kabel prategang, gaya dalam momen lentur gelagar serta gaya dalam momen lentur pylon berubah-ubah setiap tahapan konstruksinya.Hasil penelitian menunjukan terdapat perbedaan respon struktur yang dihasilkan oleh analisis langsung dan analisis sequential. Perbedaan ini memiliki nilai maksimum sebesar 19,15% untuk gaya penarikan kabel, 3,27% untuk gaya dalam kabel pada saat jembatan utuh, dan 163,04% untuk gaya dalam momen lentur gelagar.

Applied construction stages in cable-stayed bridge construction will affect its structure analysis. The resulting structural response when the analysis is done by direct analysis (full structure) without considering the staging will be different with sequential analysis prior to its construction stage.

This paper will compare the result. Therefore, the analysis needs to be carried out according to the given sequential stages. Applied cable pretension forces will be different between direct and sequential analysis. The pretension forces depend on the boundary conditions need to be fulfilled. Cable's internal tension forces, girder's and pylon's bending moment change in every phase in construction stage.

The results show that there are differences between direct and sequential analysis. The differences have maximum value 19,15% for cable’s pretension force, 3,27% for cable's internal tension force when the member of the bridge is full, and 163,04% for bending moment at girder."

"Perkembangan infrastruktur di Indonesia saat ini terbilang sangat masif dan menyebar diberbagai wilayah, sesuai dengan kebijakan Pemerintah Indonesia dalam percepatan proyek infrastruktur guna menumbuhkan dan meratakan perekonomian nasional, peningkatan kualitas hidup serta kesejahteraan manusia. Indonesia merupakan negara yang terdiri dari banyak pulau, sehingga dibutuhkan sebuah jalur penghubung seperti jembatan yang menghubungkan antara sebuah pulau dengan pulau yang berdekatan. Cable Stayed merupakan salah satu teknologi yang sangat baik dalam membuat sebuah jembatan yang terbentang panjang, mengingat tampilan akhir yang berkesan sederhana tetapi mengandung unsur estetis yang tinggi serta ketangguhannya secara struktural yang tidak diragukan. Namun, seiring dengan peningkatan sektor konstruksi, kecelakaan kerja pada bidang konstruksi juga meningkat. Merujuk data Badan Penyelenggara Jasa Sosial (BPJS) Ketenagakerjaan, secara nasional angka kecelakaan kerja sektor konstruksi tercatat sebagai sektor terbanyak nasional angka kecelakaan kerja. Terjadinya kecelakaan kerja dapat dicegah melalui sistem manajemen keselamatan dan kesehatan kerja yang baik. Manajerial keuangan dalam hal penerapan pembiayaan SMK3 di Indonesia pada sektor konstruksi khususnya pada bangunan jembatan Cable Stayed belum diatur secara jelas dan terukur. Pada pelaksanaannya, peraturan yang adapun belum sepenuhnya diikuti oleh para pelaku konstruksi bahkan di lingkungan Kementerian Pekerjaan Umum dan Perumahan Rakyat sendiri. Untuk itu perlu dibuatkan analisa struktur biaya K3 agar dapat memperkirakan biaya yang dibutuhkan dengan informasi proyek yang minimum pada tahap awal. Activity-Based Costing (ABC) atau perhitungan biaya berbasis aktivitas telah muncul sebagai pendekatan baru yang menghubungkan biaya yang terkait langsung dengan kegiatan bisnis dengan produk manufaktur. Untuk membuat perhitungan biaya berbasis aktivitas, membuat WBS dan menentukan item pekerjaan secara tepat merupakan upaya yang bermanfaat dan diperlukan untuk penilaian risiko berbasis aktivitas yang efektif. Pada dasarnya setiap jenis jembatan mempunyai komponen agar menjadi lebih kokoh, kuat maupun indah. Adapun komponen tersebut adalah sistem kabel, gelagar dan pilon. Oleh sebab itu berdasarkan informasi di atas, mengingat masih banyaknya rencana pembangunan jembatan Cable Stayed, masih tingginya angka kecelakaan kerja dan masih belum diterapkannya pembiayaan K3 secara menyeluruh di lingkungan Kementerian PUPR maka penelitian ini fokus terhadap pengembangan analisa struktur biaya K3 untuk pekerjaan komponen sistem kabel, gelagar dan pilon pada bangunan jembatan cable stayed di Kementerian Pekerjaan Umum dan Perumahan Rakyat berbasis.

The development of infrastructure in Indonesia is currently quite massive and spread in various regions, in accordance with the Government of Indonesias policy in accelerating infrastructure projects to grow and level the national economy, improve the quality of life and human welfare. Indonesia is a country that consists of many islands, so we need a connecting line like a bridge that connects between an island and adjacent islands. Cable Stayed is one of the excellent technologies in making a bridge that stretches long, considering that the final appearance is impressively simple but contains high aesthetic elements and structural toughness that is not in doubt. However, along with the increase in the construction sector, work accidents in the construction sector also increased. Referring to the Manpower Social Service Provider (BPJS) data, nationally the number of occupational accidents in the construction sector is recorded as the highest national sector work accident rate. Occupational accidents can be prevented through a good occupational safety and health management system. Managerial finance in terms of the application of SMK3 financing in Indonesia in the construction sector, especially in the cable stayed bridge building has not been clearly and measurably regulated. In its implementation, the existing regulations have not yet been fully followed by the construction actors even within the Ministry of Public Works and Public Housing itself. For this reason it is necessary to make an analysis of the K3 cost structure in order to estimate the costs needed with minimum project information at an early stage. Activity-Based Costing (ABC) or activity-based cost calculation has emerged as a new approach that connects costs directly related to business activities with manufactured products. To make activity-based cost calculations, making WBS and determining work items appropriately is a useful effort and is needed for effective activity-based risk assessment. Basically every type of bridge has components to be more sturdy, strong and beautiful. The components are cable, girder and pilon systems. Therefore, based on the information above, given the large number of plans for the construction of the cable stayed bridge, the high number of occupational accidents and the lack of comprehensive OHS funding within the Ministry of PUPR, this research focuses on developing the K3 cost structure analysis for cable system component work, girders and pilons in the cable stayed bridge building at the WBS-based Ministry of Public Works and Public Housing."
