摘要
以某座大跨度连续刚构桥的体外预应力加固工程为例,运用有限元分析软件ANSYS,分别对混凝土和钢结构转向块进行了受力分析,通过对比两类转向块在体外预应力作用下的结构内力理论计算值,分析了两类材质应用于转向块的受力特性差异,以期为同类工程提供参考。
In a external prestress reinforcement of large span continuous rigid frame bridge as case,using of FEM software ANSYS to analysis concrete and steel rotation block. Comparing with the mechanical properties of two types rotation block under the external prestress,analysis of the different characteristics about the two kinds of material,and hope to provide reference for similar projects.
