摘要:
桥梁结构在使用过程中,由于荷载作用会产生结构变形,当变形超过一定限值时,就会影响到桥梁结构的承载稳定性。在现实中通过理论计算来得到桥梁结构的变形值,其工作量是相当大的,甚至有时会很难计算,通过试验和有限元分析计算能够较好的得到桥梁的变形值。本文通过T型试验梁在不同损伤程度下的变形试验值与ABAQUS有限元模拟值进行对比分析研究,发现两者能够较好的吻合,可以运用ABAQUS对桥梁结构进行模拟分析,并依据模拟分析计算的结果来判断桥梁承载稳定性。

Abstract:
Bridge structure in using process, can produce structural deformation due to load, when the deformation exceeds a certain limit, it will affect the bearing of the bridge structure stability. In the reality through the theoretical calculation to get deformation value of the bridge structure workload is very big, even sometimes it is difficult to calculate, the accurate deformation values of the bridge structure can be obtained by experiment and finite element calculation Through the T test beam under different damage degree of deformation test value and ABAQUS finite element simulation of comparative analysis and research, found that one can better matches, can use ABAQUS simulation analysis was carried out on the bridge structure, and according to the results of simulation analysis and calculation to determine bridge bearing stability.
