《建筑抗震设计规范》(GB 50011-2001)有关问题研究

对《建筑抗震设计规范》(GB50011-2001)进行研究,指出规范存在以下问题:侧移是否满足要求,本应在设计之初就确定,但规范的缺点是,设计完成之后,才能确定塑性侧移是否满足,此时,侧移计算已经失去指导作用;规范规定计算两个侧移是不必要的,因为起控制的只有一个侧移;地震区框架最大适用高度值有误,应予以折减;防震缝宽度经实际地震检验,证明严重偏小,应大幅度加宽;填充墙框架抗震防线数有误,不是两道,而是一道,并对以上问题提出修正建议。

RESEARCH ON THE PROBLEMS RELATED TO "CODE FOR ASEISMIC DESIGNOF BUILDINGS"(GB 50011-2001)

It was carried out the research on the problems related to "The Code for Aseismic Design of Buildings "(GB 50011-2001).The problems existed in the code were pointed out as follows:whether plastic sidesway met the demands or not should be originally confirmed while design beginning.But defect of code was that it was confirmed when design was finished.In fact,at this time sidesway calculation did not have the guidance function.The code stipulates that two sidesways must be calculated was unreasonable,because only one was enough.The maximal suitable height of the frame in seismic areas was obviously mistaken,which should be reduced.Actural earthquake hat proved that the width of seismic joint was too small.Which should be widened to a large margin.Infilled frame in seismic area had two steps of seismic resistance was wrong.Because there was only one step.Finally,the suggestions on solving the above problems were proposed for revision of the code.
