摘要
基于双线性水平力-位移骨架曲线对12种单层钢框架进行静力分析,将得到的极限位移与有限元法对框架进行动力稳定性分析得到的极限位移作以比较,结果表明,两者基本接近,误差均在5%之内,并且与按抗震规范和实际工程要求计算框架结构的极限位移进行对比。通过分析,为单层框架结构防倒塌设计时极限位移及可能震害程度的确定,提供可参考的依据。
Static nonlinear analysis to 12 kinds single-story frames is analyzed based on bilinear lateral force versus displacement framework curve,then ultimate displacements are compared with dynamic collapse ultimate displacement obtained by dynamic stability analysis with ANSYS program.The results are close,and the differences of them are all within 5%.Moreover,according to present aseismatic code and practical engineering,ultimate elastic-plastic displacement are calculated and compared.By the analysis to ultimate displacement of single frame,some references are provided for determining ultimate displacement and possible damage brought by the earthquake.
