PERANCANGAN ULANG STRUKTUR ATAS JEMBATAN BAJA TIPE SUBDIVIDED WARREN

Studi Kasus : Jembatan Kelutan - Papar

Abstract

The Kelutan - Papar Bridge was built across the Brantas River to connect the Nganjuk and Kediri borders. Intends to redesign the bridge with the title "Redesign of the Upper Structure of the Subdivided Warren Type Steel Bridge on the Kelutan - Papar Bridge". The purpose of this re-planning is as an alternative to the bridge design if there is a redesign of the Kelutan - Papar bridge.Re-planning the upper structure of the bridge from previously using 3 superstructures to 2 superstructure and using 1 pillar, in order to find bridge efficiency. Using the Load and Resistance Factor Design (LRFD) method and refers to the latest SNI rules. This planning is assisted by using the StaadPro V8i SS6 structural application program to analyze the structure of the bridge.The structure of the superstructure of the Subdivided Warren Truss type bridge consists of several main parts, namely the elongated girder with a bolt size of Ø24 mm with a connecting plate L 100 x 100 x 10 mm, a transverse girder and a main bolt measuring Ø24 mm with a connecting plate L 100 x 100 x 10 mm , The connection between the join of the main girder and wind ties with a diameter of Ø24 mm with a plate thickness of 21 mm. As for the results of the planning and analysis obtained, the structure of the structure of the bridge uses WF profiles 350 x 175 x 7 x 11 (longitudinal girder), WF 900 x 300 x 16 x 28 (lower transverse girder), WF 350 x 350 x 12 x 19 (top girder), WF 400 x 400 x 13 x 21 (main girder), 2L 250 x 250 x 25 (wind bond).
