Abstract

Abstract: Based on analysis and generalization of the existent calculating methods of bridge transverse load-distributing influence lines, A new method is proposed in the paper with the bridge transverse formation simulated as a usual plane finite bar element model in a computer software. The software realizes automatic modeling and calculating of bridge transverse load distribution according to the bridge transverse structural features, and its rightness and convenience warranted in the given calculation

Key words: bridge, transverse distributing influence lines, plane finite bar elements
