STUDY ON COMPOSITE BEHAVIOR OF HYBRID FRP-CONCRETE BRIDGE SUPERSTRUCTURE SYSTEM

摘要：

This paper presents analytical studies of an innovative hybrid FRP-concrete bridge superstructure system. Three rectangular GFRP box sections were bonded together to form the tensile layer,and a layer of concrete was placed in the compression zone of those sections. This new design was proposed in order to make the best of each constituent material,and to increase stiffness of GFRP composite structures. Numerical simulations were performed by using finite element method (FEM) and comparisons were made to observe the difference of the mechanical behaviour. According to the analysis of the analytical data,we can draw some instructive conclusions which can provide some references for applications.
