Modeling of the Mechanical Characteristics of the Prefabricated Cantilever Structure

Abstract

The prefabricated cantilever composite subgrade structure is a special and new type of structure suitable for the construction of mountain roads or the renovation and widening of old roads, but its related research is less. In order to reveal the mechanical response performance of precast cantilever composite subgrade structure, ABAQUS finite element software was used to model the mechanical response of such a unique structure. The results demonstrated that using a prefabricated structure and the integral modeling method increases the security of the tranverse displacement response of the column. The primary stress components of the constructed cantilever structure are not significantly affected by changes in steel plate thickness. The main load-bearing elements of the prefabricated cantilever structure are not significantly affected by changes in column concrete strength grade.
