PERENCANAAN JEMBATAN RANGKA PANDHAWA TIPE ARCH

Abstract

Bridges are important infrastructure in the transportation system, namely as a medium for crossing rivers, as well as connecting cliffs. This bridge is an arch bridge with cables. The arch bridge is suitable for the Pandhawa bridge because it has a fairly long span. Through the preparation of this thesis, the author tries to plan an alternative building on an existing bridge with an arch type. Initial planning data includes the length of the existing bridge 100 m wide 9 m. The planning method used is LRFD (Load Resistance Factor Design) and uses the SAP2000 program. In this plan the author plans floor slabs, longitudinal girders, transverse girders, main girders, wind ties, cables, connections and elastomers. From the results of the analysis, the structure of the bridge superstructure for the floor slab uses the main reinforcement D16-150 and the reinforcement for D13-200, the longitudinal steel profile girder WF 350 x 350 x 14 x 22, the transverse girder steel profile WF 700 x 400 x 14 x 32, WF 800 x 400 x 40 x 40 profile steel main girder, double L profile steel wind ties 250 x 250 x 35, for dyform 6 hanging cable dimensions, for laying using elastomer length 110 cm, width 110 cm, height 32 cm.
