| 摘 要： | 基于美国规范ATC-40和N2方法,建立了大跨预应力混凝土框架结构竖向地震反应的静力弹塑性(pushover)分析方法。编制了预应力混凝土构件截面弯矩-曲率的计算程序。这些为评价大跨预应力混凝土框架结构的竖向抗震能力提供了有益的参考。结合具体工程实例进一步说明了该方法的实施步骤。

| Abstract: | Based on ATC-40 and N2 method, the nonlinear static procedure (pushover analysis) was developed for coping with the vertical seismic response of large-span prestressed concrete frame structures. A computational program was developed to deal with the relationship between the section-moment and the curvature in the prestressed beams. These render a beneficial reference to evaluate the anti-earthquake performance of large-span prestressed concrete frame structures. Further, a practical engineering is used to demonstrate the application of proposed nonlinear static procedure. |
