Study on Equivalent Vehicle Loading on Panel of Trestle Bridge for Excavation

Abstract

Earthwork vehicle is the main construction vehicle that runs on the trestle bridge of excavation. The latest Load code for the design of building structures has not yet provided the equivalent vehicle loading on the trestle bridge panel in China. Considering the number of earthwork vehicles, the span and the thickness of the trestle bridge panel and other factors, the unfavorable distribution of wheels of earthwork vehicle had been analyzed. The equivalent uniformly distributed vehicle loading was obtained by means of the software ABAQUS. The results may be the references to the designers of the trestle bridge for excavation.
