Study on Load of Middle and Small Span Highway Beam Bridge

Abstract

The magnitude of the load is the main reason for the direct impact of highway bridge safety. With the increase in transport demand, vehicle overload phenomenon gradually increased. In recent years, repeated heavy vehicles crushed the bridge accident, causing widespread concern in society. In this paper, the load characteristics of the bridge are analyzed by ANSYSY finite element simulation. And provide a useful reference for the design and construction of highway bridge structure.
