Abstract

The frame bridge is a structure commonly used in the manufacture of bridge construction in Indonesia. Steel-frame bridges have several forms, one of which is a truss bridge. The truss bridge is composed of rods connected to each other. According to RSNI-T-03-2005, deflection on the bridge is limited to not exceeding l / 800 span length. This research was conducted to analyze the value of deflection, and the permissible limits according to the RSNI-T-03 2005 which occurred in the trusses due to the combined load with the maximum design wind speed in the last 10 years (2010-2019) taken from NOAA (National Oceanic). and atmospheric Administration) of 103.6 m / s. From the analysis of the deflection value that occurs on the steel frame bridge, the value of each bridge span is as follows: At a span of 50 m, the allowable deflection limit is 0.0625 m. So on the X-axis, there are 2 load combinations whose deflection values exceed the allowable limit, on the Yaxis, for the entire loading combination meets the deflection permit limit and on the Z-axis, it does not meet the deflection permit limit. At a span of 60 m, the allowable deflection limit is 0.075 m. So on the X axis, it fulfills the permit limits, on the Y axis, for the whole load combination meets the deflection permit limit and on the Z axis, there are 3 load combinations that meet the deflection permit limits, namely Strong 4, extreme 2 and Service 4.
