THERMAL STRESS ANALYSIS OF HYBRID FRP-CONCRETE BRIDGE SUPERSTRUCTURE
摘要
Abstract
Finite element method has been employed to study the structural performance of one kind of hybrid fiber reinforced polymer ( FRP) -concrete bridge superstructure under thermal effects using commercial finite element analysis (FEA) software, ABAQUS. Three kinds of ambient temperature change are chosen in this paper, which are two kinds of uniform temperature change and one kind of gradient temperature change. This study describes the conditions of deformation and stress distribution for the hybrid FRP-concrete bridge superstructure under the three kinds of temperature change. FEA results indicate that the thermal response of the hybrid FRP-concrete bridge su perstructure would be significant, and the thermal effects should be considered as one of the important effects in the structural design of hybrid FRP-concrete bridge superstructure.关键词
