Perencanaan Struktur Atas Jembatan Sungai Baki Menggunakan Jembatan Struktur Baja Komposit (Studi Kasus : Desa Tanjung Pisang Jembatan Sungai Baki)

Abstract

In general, the type of bridge is conventional, reinforced concrete, composite and cable stayed. The baki river bridge was originally a 40 m long wooden type bridge linking the village of Mengkopot – Tanjung Pisang. Due to the condition of the baki river bridge that has been damagen on the bridge floor due to age, it was tried to be re-planned using the steel bridge strukture, it is expected that later it can be a comparison for the future bridge planning. In this thesis, bridges are planned using composite struktures between steel girders and concrete slabs. This plan ferers to SNI T-02-2005bridges and SNI T-03-2005 for steel strukture planning. The plan is to include girders, diaphragms, slab and bridge back posts. From the results of the planning, the steel girder profile used is WF 500 x 200 x 10 x 16 mm with a gap between 1,75 m. The steel elbow profile diaphragm is used 90 x 90 x 9 mm with a diaphragm distance of 4 m, the elastomeric placement diameterr is 175 x 300 x 12 mm.
