建筑抗震韧性的概念和评价方法及工程应用

Resilience-based seismic performance concept,assessment methodology and engineering application

从城市韧性和建筑抗震韧性两个层面对韧性的概念进行了介绍,通过对基于规范的抗震设计、基于性能的抗震设计和基于韧性的抗震设计这三种抗震设计方法进行的比较分析,阐述了传统设计方法的局限性和基于韧性的抗震设计方法的优越性。最后,介绍了奥雅纳公司主导开发的建筑抗震韧性评价体系REDiTM以及其在美国旧金山市的实际工程项目中的应用情况。

The concept of city resilience and building seismic resilience was introduced. Based on the comparative analysis of code-based,performance-based and resilience-based seismic design method,limitations in traditional seismic design procedures were identified. Resilience-based seismic design is considered as a more meaningful and useful seismic design,planning and assessment approach. For its implementation, ARUP created the Resilience-based Earthquake Design Initiative（ REDi^TM） Rating System. The REDi^TM framework and its engineering application were introduced.
