轴压比对扁梁节点抗震性能影响的有限元分析

The FEA analysis about the effect of axial force ratio on seismic behavior of joints of prestressed concrete flat beam

本文探讨了如何利用有限元方法模拟分析轴压比对预应力混凝土扁梁框架内节点抗震性能影响的方法,并通过3个不同轴压比的预应力混凝土扁梁框架内节点试件的低周反复荷载加载试验进行验证。

Using FEA analysis program,this paper simulates the whole collapse process of inner joints of prestressed concrete flat beam under monotone loading test to research the influence of the axial force ratio to the seismic performance.By the way,the pseudo-static test of three inner joints of prestressed concrete flat beam frame was carried out to compare with the results of the FEA analysis.
