摘要
结合国际地震工程界提出的新一代基于性能的地震工程的框架方法,重点阐述了性能评估中涉及的主要问题。对性能评估使用的静力非线性分析、动力非线性分析方法进行了总结,在此基础上详细阐述了在基于概率的性能评估中有应用前景的增量动力分析方法的概念、相关问题及其应用,并简要介绍了基于增量动力分析思想提出的一些简化方法。最后提出了今后研究的建议,特别是结构非线性分析方面的研究重点。
The main issues of performance evaluation are discussed with the introduction to the framework methodology of new generation of performance-based earthquake engineering proposed by international earthquake engineering profession. Present nonlinear analysis procedures for performance evaluation, such as nonlinear static analysis and nonlinear dynamic analysis, are reviewed, respectively. Then, the concept, the associated issues and the application of incremental dynamic analysis （IDA） approach, a promising method for probability-based performance evaluation, are discussed in detail. Furthermore, some simplified approaches based on IDA concept are introduced briefly. Finally, some recommendations for future research are presented, especially for structural nonlinear analysis.
