| 摘 要： | 对交错桁架结构抗震性能的研究很少。采用壳单元和梁单元相结合的三维非线性有限元分析模型,分析了一个混合式交错桁架结构在循环荷载作用下的性能,与试验结果比较表明,此计算模型精确、高效。对此模型进行了循环荷载下的滞回性能分析。结果表明,该结构体系具有较好的耗能能力和抗震性能。

| Abstract: | The research on seismic performance of staggered truss frame structures is very rare.A nonlinear finite element model is induced for analyzing the composite staggered truss steel structure system under cycle load,in which the shell and beam element are applied.It is shown by computed examples that simulation of presented model is accurate and efficient.A hysteresis analysis is made under cyclic load,and the results show that the composite staggered truss steel structure system has better seismic performance. |
