| 中文摘要 | 静力弹塑性方法作为一种评价结构抗震性能和计算结构弹塑性变形的简化方法,近年来得到了广泛应用。但由于传统的定侧力模式的静力弹塑性方法只考虑第一振型,无法反映高层建筑结构的高阶振型影响。为考虑高阶振型的影响,Chopra在振型分解反应谱组合法的基础上,提出了MPA方法。本文首先讨论了应用MPA方法需注意的问题,然后用一个18层钢筋混凝土框架—剪力墙结构为算例,以逐步增量弹塑性时程分析结果为基准,对传统定侧力模式静力弹塑性方法和MPA方法的分析结果进行了对比研究。结果表明,相比于定侧力模式静力弹塑性分析结果,MPA方法的分析结果更接近弹塑性时程分析结果。; Nonlinear static analysis(or pushover analysis) has been widely used recently as a simplified method to evaluate the structural seismic performance and estimate inelastic structural responses under severe ground motions.But most traditional pushover procedures,which have fixed lateral load patterns that are major based on first structural modal,can not reflect the effect of the higher modal on the structural dynamic response.To overcome this problem,Chopra et al.has proposed a new pushover procedure which is referred as modal pushover analysis(MPA) based on the modal decoupling response spectrum method to consider the effect of the higher mode.Currently,most MPA research is focused on frame structures.In this paper,the problem of MPA when it is implemented in frame-shear-wall structures is high lighted together with proposed solution method.An eighteen-story reinforced concrete frame-shear-wall structure is used as an example to benchmark the accuracy of traditional pushover method and MPA method.The structural responses with MPA method and traditional pushover methods are compared with the results of incremental nonlinear dynamic time history analysis,which shows that MPA procedure gives better prediction for inelastic responses of the structure. |
