A Bridge Girder Ab On A Simple Span Of Length L 23 M Supports A Distributed Load Of Maximum Intensity Q At Mid Span An 1 (44.9 KiB) Viewed 43 times

A bridge girder AB on a simple span of length L = 23 m supports a distributed load of maximum intensity q at mid-span and minimum intensity 9/2 at supports A and B that includes the weight of the girder (see figure). 9 450 mm 9 9 comitom 32 mm A B L = 23 m 16 mm 1800 mm 32 mm 450 mm The girder is constructed of three plates welded to form the cross section shown. Determine the maximum permissible load 9 (in kN/m) based upon the following. (a) solely based on an allowable bending stress o allow = 110 MPa kN/m (b) solely based on an allowable shear stress T allow = 50 MPa KN/m (c) accounting for both an allowable bending stress allow and an allowable shear stress Tallow kN/m
