Evaluasi Perhitungan Struktur atas Jembatan Beton Prategang di Sibolga

Abstract

Aek Kaludi 1 pre stressed concrete bridge is one of the alternative road connecting bridges from Rampa to Poriaha Sibolga with a total bridge length of 16.60 meters and a total bridge width of 11.6 meters. The design of Aek Kaludi 1 pre stressed bridge is based on T-12-2004 National Hospital for loading on bridges, RSNI T-02-2005 for processing concrete used for bridges, and Manual 021 / BM / 2011 planning pre stressed concrete structures for bridges. From the calculation results of loading and reinforcement found floor plate loading due to own weight = 5 kN / m, additional dead load = 2.69 kN / m, Trukal = 157.5 kN, wind load = 0.648 kN, various temperature loads = 12 , 5 derajat C and floor plate reinforcement for negative flexural reinforcement D16-85 mm and positive bending reinforcement D16-90 mm. Transverse plate crossing D13-160 mm and longitudinal direction D16-180 mm. Pre-stress beam loading on pre-stressed body weight = 6.125 kN / m, additional dead load = 5.2455 kN / m, lane load = 17.550 kN / m, brake force = 19.34 kN / m, wind load = 0,741 kN / m , seismic load = 3,461 kN / m and pre stressed beam bone as much as 20 bars with a diameter of 13 mm.
