| 摘 要： | 阐述了Conventional Pushover分析法的基本原理和方法，指出固定侧向力加栽模式的缺陷：由于Adaptive Pushover分析法考虑了结构刚度退化、高阶振型的影响、地震反应谱理论以及SRSS或CQC振型组合的综合作用，同固定侧向力加栽模式相比，对结构受力状态的模拟更加准确。指出Pushover分析法尚存在的问题。

| Abstract: | This paper reviews the basic principles and methods of the conventional pushover analysis,and indicates the intrinsic shortcoming of the pattern loaded with fixed lateral force. Since it considers the synthetic effect of the structural stiffness degradation, influence of higher modes of vibration, the spectral acceleration theory and the SRSS or CQC combination of modes, the adaptive pushover analysis is more accurate than the pattern loaded with fixed lateral force in simulating the structural stress state. Finally, some suggestions are proposed for the development of Pushover analysis. |
