摘要
基于性能的抗震设计(PBSD)是现代工程抗震理论研究的重要问题。与传统抗震设计方法相比,基于性能的抗震设计可反映具体结构的抗震性能目标。本文在综述基于性能的抗震设计理论的背景、概念、主要内容的基础上,根据钢管混凝土结构的特点,较系统地分析了钢管混凝土框架基于性能的抗震理念和设计方法,讨论了基于位移的抗震设计(DBSD)应用于钢管混凝土结构时的方法和步骤,并对确定该类结构的目标位移和相应的侧移模式进行了初步探讨。采用SAP2000软件建立了某12层钢管混凝土框架模型并进行了静力推覆(pushover)分析,初步评价了地震作用下钢管混凝土框架结构的性能指标。
The theory of performance-based seismic design(PBSD) is key issue in the modern earthquake engineering research.By the comparison with the traditional seismic deign method,the PBSD presents the specific performance objective of the structure.In this paper,the PBSD method for the concrete-filled steel tubular(CFST) structure is analyzed based on the background,concept and main content of PBSD.The PBSD methods and approaches for CFST structures are discussed based on the mechanical behaviors of the CFST structures.The target displacement and the initial mode of lateral displacement of CFST structures are determined.A 12-stories CFST frame structure model is analyzed by pushover method with SAP2000,and the preliminary performance index of the CFST frame structure under earthquake is evaluated.
