Abstract

Suspension bridge is a type of bridge which have the deck hung below the suspension cables on vertical suspenders. The bridge is commonly used for long spans. One of the longest suspension bridge is Akashi-Kaikyo in Japan. Cost effective, suitable for long span bridge, have more flexibility and less complicated construction are the advantage of suspension bridges. Therefore suspension bridges are not only designed for vehicles but also for pedestrians. Suspension bridges for pedestrian are usually located in rural areas due to obstacles such as rivers, valleys or plantations. This paper presents a design of suspension bridge for pedestrian. The design refers to “Manual for Design and Build of Suspension Bridge for Pedestrian”. The suspension bridge is modeled using MIDAS Civil 2019. The output of the software is the internal forces consisting of moments, shear and normal forces used to design section properties and connection models. Based on the analysis and design process, obtained the dimensions of the bridge element; IWF.250.125.9.6 for the main girder, 150.100.9.6 for the cross girder, C.50.45.5.7 for the secondary girder, 250.250.14.14 for the pylon, L.50.50.5 for the bottom bracing, 60 mm for the main cable diameter, 20 mm for the hanging rod diameter, and 20 mm for the wind cable ties diameter.
