摘要
本文对基于功能的结构抗震设计中的一些问题进行了探讨，指出未来基于功能的结构抗震设 计应具备如下主要特点：分别考虑反映结构抗震设计“共性”和“个性”的两类目标功能水平；直接采 用可靠度的表达形式，并将结构构件层次的可靠度应用水平过渡到考虑不同功能要求的结构体系可 靠度水平上；采用“投资－效益”准则下的基于可靠度的结构优化设计方法。
Some key problems on performance-based seismic design are discussed in the present paper. It is concluded that the future performance-based seismic design should contain the following characteristics. (1) The design process should consider two types of target performance levels, which reflect the 'generality' and 'individuality' of seismic design respectively. (2) The reliability-based format is used directly, and the application of reliability in member level should be improved to that in structural system level considering different seismic performance requirements; (3) Reliability-based structural optimization procedure under cost-benefit criterion should be employed.
