摘要

汶川地震后,《建筑抗震鉴定标准》GB50023及时进行了修订,并于2009年7月1日正式实施。本文对新版鉴定标准的主要修订内容进行了介绍,包括现有建筑抗震设防水准的规定,现有建筑后续使用年限的概念及确定方法,不同后续使用年限建筑的抗震鉴定方法,以及重点设防类建筑的抗震鉴定要求等。
After Wenchuan Earthquake,the revision of "Standard for seismic appraisal of buildings GB50023-95" has been carried out.The new standard GB50023-2009 was put into effect on July 1st this year.In this paper,the main issues in the revision of GB50023-2009 were introduced,include:(a)clarification of seismic fortification level of existing buildings,(b)introduction of continuous seismic service life of existing buildings,(c)classification of existing buildings according to construction age or corresponding design code series,called category A,B and C,(d)seismic appraisal methods of buildings with different continuous seismic service life,(e)improvement of seismic fortification criterion for those buildings of major fortification category,such as school or hospital buildings.
