RESEARCH ON THE PROBLEMS RELATED TO "CODE FOR ASEISMIC DESIGN OF 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.
