基于通用有限元软件ABAQUS的子结构拟动力试验研究
|
摘要
通过OpenFresco试验协调系统,实现通用有限元软件ABAQUS与MTS电液伺服加载系统的数据传递,采用子结构拟动力试验方法开展单层单跨钢结构框架在地震作用下的反应分析。通过有限元软件模拟结果与试验结果的对比,证明该试验方法的结果与模拟结果一致。采用OpenFresco试验协调系统不仅能够实现结构构件层次上的子结构拟动力试验,而且能够使计算子结构部分进入塑性,极大地扩展了拟动力试验的功能。
Pseudodynamic substructure testing was adopted to simulate seismic response of steel frame,while OpenFresco exchanged data between the finite element software ABAQUS and electro hydraulic servo system MTS.By comparing the results between pseudodynamic substructure testing and finite element software simulation,they accorded approximately.It is turned out that pseudodynamic substructure testing with OpenFresco can research sub-component of structures experimentally,and this method can simulate the numerical substructure in nonlinear.The function of pseudodynamic substructure testing is widely expanded.
