STUDI ALTERNATIF PERENCANAAN STRUKTUR ATAS JEMBATAN MENGGUNAKAN DESAIN A HALF THROUGH ARCH

Studi Kasus : Jembatan Soekarno-Hatta, Kota Malang

Abstract

Soekarno-Hatta Bridge in Malang City, which has a level of traffic density in its development until now, has undergone strengthening due to structural fatigue and almost entering the fatigue age of a bridge. With this in view of the fairly dense function of transportation facilities, the Soekarno-Hatta Bridge was built to support access in the city of Malang. In this planning, Soekarno Hatta Bridge is planned using the construction method A Half Through Arch with Hanging Cables in a span of 100 meters without central pillars and the Load and Resistance Factor Design method (DFBK) and refers to the latest SNI rules. This planning is assisted by using thestructural application program StaadPro V8i SS6 to analyze the structure of the bridge.After analyzing the upper structure of this bridge, the dimensions of the steel structure for the main girder were obtained using a WF profile 400.400.45.70, longitudinal girder WF profile 400.200.8.13, transverse girder under profile WF 850.350.16.36, upper transverse girder WF 350.350.12.19, Wire hanging cables 6x37 IWRC Ø38 ropes, 2L 150.150.19 atss wind tie girders, and 2L 250,250.35 downwind bond girders.
