摘要
新的《建筑抗震设计规范》(GBJ11-89)已于1989年3月27日批准,其中提供了不对称建筑抗震计算方法的规定,弥补了现行《工业与民用建筑抗震设计规范》(TJ11-78)的不足。本文针对新规范有关条文,推导了每楼层质心处三个地震作用公式的来源,介绍了完全二次型组合(CQC)方法,并通过震害实例分析表明按理论计算结果与实际震害相符。
The new 'China Seismic Design Code for Buildings' (GBJ 11-89) was approved by the Ministry of Construction on March 27, 1989 and will be put in force from January 1, next year. The new code provisions for seismic calculation of asymmetric buildings, filling the blank in the current seismic design code (TJ 11-78).
This paper explains the items concerning provisions for seismic calculation of asymmetric buildings in the new code and gives derivation of the formulae involved. Analysis results of some earthquake-stricken buildings by the new method agree very well with the damage observed.
