Determining load rating capacity of simple log stringer bridges Lee, Michael

Abstract

This essay uses referenced values of allowable stresses to determine the load rating capacity of a constructed Douglas Fir Log Stringer Bridge. This method compares the applied moments and shear stress from the live vehicle load and the weight of the bridge to the allowable moments and shear stress the bridge is designed to support. The factors which affect the load rating capacity are stringer diameter, depth of gravel decking, span length, stringer species and eccentricity of load. It has been determined that this bridge is capable of safely supporting the Ministry of Forests L-60 On-Highway vehicle loading standard.
