摘要
为评估建筑物在地震中的抗震性能是否满足预期的要求,对其进行非线性时程分析是一种重要的技术手段。本文以某钢结构建筑物为实例,基于SAP2000有限元软件,对楼层最大加速度、最大位移、倒塌弯矩、楼层剪力进行了数值仿真计算和试验研究。通过数值仿真结果与试验进行比较,结果表明:数值模型可较好的模拟结构的非线性行为,且采用建议的数值模型参数设定,对实际结构进行分析,可在建造初期有效的评估建筑结构的抗震性能,是一种简便有效的工程设计方法。
In order to evaluate the seismic performance of building, the nonlinear time history analysis is an important technical means to analysis the seismic performance. Taking a steel structure building as an example, the numerical simulation and experimentthe maximum displacement, the collapse moment and the floor shear of the building are carried out based on SAP2000 finite element software. By comparing the numerical simulation with the experiment, the results show that： numerical model can be used to simulate the nonlinear behavior of the structure, and the proposed numerical model parameters are used to analyze the actual structure, which can effectively evaluate the seismic performance of the building structure at the beginning of the construction. It is a simple and effective method for engineering design.
