摘要: 日本《建筑基準(zhǔn)法》只是規(guī)定了保護(hù)人類生命的最低水準(zhǔn)的抗震性能,這往往不足以滿足地震后維持建筑物功能和業(yè)務(wù)連續(xù)性的需求. 如果建筑物抗震性能不同,即使是遭遇相同的地震,地震后建筑物的狀態(tài)也會(huì)不同.為了滿足業(yè)主的多樣化需求,有必要通過與業(yè)主溝通,明確相應(yīng)的抗震性能目標(biāo),進(jìn)行性能設(shè)計(jì). 本文展示了地震大小與建筑物受損程度之間的關(guān)系,建筑的震后受損程度以及性能設(shè)計(jì)的流程,最后提供了性能選單表和性能診斷表供設(shè)計(jì)人員參考使用.

The guide to safe buildings JSCA performance-based seismic design

Japan Structural Consultants Association

Abstract: Japanese building standards law only stipulates the minimum level of seismic load to protect human life, which isoften not enough to meet the needs of maintaining building functions and business continuity after an earthquake. If thebuilding’s seismic performance is different, even if it encounters the same earthquake, the state of the building after theearthquake will be different. In order to meet the diverse needs of the owners, it is necessary to communicate with theowners to clarify the corresponding seismic performance level and carry out performance-based design. This article showsthe relationship between the earthquake scale and the building damage state, the building damage state after theearthquake, and the process of performance-based design. Finally, it provides a performance menu table and a performancediagnosis table for the reference of designers.

Keywords:performance-based design; performance menu; seismic performance level; building damage state; performancevalue table; performance diagnosis table
