ABSTRAKUntuk mendukung pembangunan infrastruktur jembatan, pemerintah mengeluarkan panduan untuk perencanaan jembatan gantung dengan judul Surat Edaran Menteri Pekerjaan Umum No. 02/SE/M/2010 tentang Pemberlakukan Pedoman Perencanaan dan Pelaksanaan Konstruksi Jembatan Gantung Untuk Pejalan Kaki. Jembatan gantung yang dirancang sesuai dengan panduan tersebut harus mampu menahan beban pejalan kaki sebesar 5 kPa. Dengan mengacu pada pedoman tersebut, direncanakanlah sebuah jembatan gantung dengan panjang total 127.34 meter. Agar dapat mengetahui perilaku jembatan terhadap beban yang direncanakan, dibuatlah pemodelan jembatan menggunakan software MidasCIVIL dengan menggunakan 4 variasi letak pembebanan dan 80 variasi beban mewakili bobot pejalan kaki dan kendaraan bermotor roda dua. Tujuan dilakukannya analisis ini adalah untuk mengetahui nilai keandalan struktur yang direncanakan dengan beban sesuai Surat Edaran Menteri Pekerjaan Umum No. 02/SE/M/2010 terhadap variasi beban pejalan kaki dan kendaraan bermotor yang sesungguhnya mungkin terjadi pada jembatan. Evaluasi struktur menggunakan metode probability based menghasilkan keandalan struktur jembatan sebesar 100% yang dianalisis terhadap lendutan, tegangan kabel, tegangan batang penggantung serta tegangan pilar. Sehingga dapat dikatakan bahwa beban 5 kPa yang disyaratkan oleh pedoman memiliki nilai yang konservatif dan akan menghasilkan struktur jembatan yang sangat aman.Kata kunci: : Jembatan Gantung, Variasi Letak Beban, Pejalan Kaki, Probability Based Design ABSTRACTTo support the establishment of bridge infrastructure, the government issued a guide for planning a suspension bridge with the title Surat Edaran Menteri Pekerjaan Umum No. 02 / SE / M / 2010 concerning the Implementation of Guidelines for Planning and Construction of Suspension Bridges for Pedestrians. Suspension bridges designed according to these guidelines must be able to withstand pedestrian loads of 5 kPa. With reference to these guidelines, a suspension bridge is planned with a total length of 127.34 meters. In order to know the bridge's behavior towards the planned load, a bridge modeling was made using MidasCIVIL using 4 position of loading and 80 load variations representing pedestrian weight and two-wheeled motorized vehicles. The purpose of this analysis is to determine the value of the bridge reliability that planned with load according to the Surat Edaran Menteri Pekerjaan Umum No. 02 / SE / M / 2010 against variations in pedestrian and motor vehicle loads that might actually occur on bridges. Structural evaluation using probability-based methods produces 100% bridge structure reliability which is analyzed for deflection, cable stress, hanger stress and pillar stress. So, it can be said that the 5 kPa load required by the guidelines has a conservative value and will produce a very safe bridge structure.Keywords: Suspension Bridge, Load Position Variation, Pedestrian, Probability Based Design

The flexibility and low damping of the long span suspended cables in suspension bridges makes them prone to vibrations due to wind and moving loads which affect the dynamic responses of the suspended cables and the bridge deck. This paper investigates the control of vibrations of a suspension bridge due to a vertical load moving on the bridge deck with a constant speed. A vertical cable between the bridge deck and the suspended cables is used to install a hydraulic actuator able to generate an active control force on the bridge deck. Two control schemes are proposed to generate the control force needed to reduce the vertical vibrations in the suspended cables and in the bridge deck. The proposed controllers, whose design is based on Lyapunov theory, guarantee the asymptotic stability of the system. The MATLAB software is used to simulate the performance of the controlled system. The simulation results indicate that the proposed controllers work well. In addition, the performance of the system with the proposed controllers is compared to the performance of the system controlled with a velocity feedback controller.

This paper presents a reliability analysis to assess the safety of corroded main cables of a long-span suspension bridge. A multiscale probability model was established for the resistance of the main cables considering the length effect and the Daniels effect. Corrosion effects were considered in the wire scale by relating the test results from accelerated corrosion tests to the corrosion stages and in the cable scale by adopting a corrosion stage distribution of the main cable section in NCHRP Report 534. The load effects of temperature, wind load, and traffic load were obtained by solving a finite element model with inputs from in-service monitoring data. The so-obtained reliability index of the main cables reduces significantly after operation for over 50 years and falls below the design target value due to corrosion effects on the mechanical properties of the steel wire. Multiple measures should be taken to delay the corrosion effects and ensure the safety of the main cables in the design service life.
