| 摘 要： | 静力推覆分析是一种计算结构非线性响应的简化分析方法,然而标准的静力推覆分析方法不能计人高阶振型的贡献,难以应用到大跨度的桥梁结构中.有学者提出的模态静力推覆分析方法在计算结构的非线性响应时考虑了高阶振型的影响,且仍具有推覆分析方法计算量小的优点.该文使用模态静力推覆分析方法计算一座实际桥梁结构的非线性反应,并与标准的推...

| Abstract: | The pushover analysis is a simplifying analysis method to assess the nonlinear performance of structures,but it is hard to be used in the long span bridge structures because of the standard pushover analysis method not able to take the contribution of higher mode into account. The modal pushover analysis method put forward by some scholars considers the influence of higher mode when assessing the nonlinear performance of structure,and still has the advantage of the low computational cost as standard pushove... |
