基于“投资-效益”准则的抗震性能目标优化决策
|
摘要
以结构在地震作用下的破坏程度为依据将结构性能水平划分为五级,并选取结构的层间位移角为定量控制指标,建立了"结构破坏程度结构性能水平层间位移角"之间的对应关系.该划分细化和量化了现行规范规定的三级性能水平,为设计人员和业主提供更多选择,使结构抗震设计更加灵活.同时以"投资效益"准则为基本原则,结合地震危险性分析,建立了改进的结构全寿命总费用模型.该模型不仅考虑了结构的初始造价,而且充分根据结构性能失效的特点考虑了结构在各级性能水平下的损失期望,全面注重了结构性能、安全及社会经济等因素,为实现基于性能的结构抗震设计提供了有效的理论依据和可靠的计算方法.
Based on the structure damages in earthquake,the structure performance was classified into five levels.The inter-story drift was adopted as the quantitative control index of the deformation,and the relationship among the damages,the five-level performance and the inter-story drift was also revealed.This classification was built on the basis of the three-level performance according to "Chinese code for seismic design of building(GB50011-2010)",which provided more options for designers and owners.Meanwhile,based on the "cost-effectiveness" criterion and seismic hazard analysis,a modified structural life-cycle cost model was presented.The proposed model considered not only the structural initial cost but also the failure loss expectation on different performance levels.The model is of great significance to the performance-based seismic design,which pays full attention to the performance of structures,security and social economy.
