（機械工業(yè)第三設(shè)計研究院，重慶 400039）［摘要］高層建筑底部的抗震設(shè)計至關(guān)重要，應(yīng)采取有效措施，改善結(jié)構(gòu)底部的抗震性能，避免在罕遇地震作用下由于結(jié)構(gòu)底部的破壞而造成高層建筑的整體性倒塌。結(jié)合實際工程對高層建筑的嵌固、吊腳樓等抗震問題進行了探討，并提出了一些實用的技術(shù)措施。［關(guān)鍵詞］高層建筑； 抗震設(shè)計； 嵌固端； 吊腳樓Discussion on several problems in seismic design of the bottom of high-rise buildingsWang Zuo(China CTDI Engineering Corporation， Chongqing 400039, China)Abstract:Seismic design of the bottom of high-rise buildings is very important. In order to improve seismic performance of the bottom structures and avoid the overall collapse of high-rise buildings caused by serious damage of the bottom structures under rare earthquake, effective measures should be taken. Several problems of the bottom of high-rise buildings, such as constrained part and stilted building were discussed. Some practical measures for seismic design of the bottom of high-rise buildings were provided.Keywords:high-rise building； seismic design； constrained part； stilted building作者簡介：王佐，碩士，高級工程師，一級注冊結(jié)構(gòu)工程師，Email：cq-wz@163.com。參考文獻［1］ JGJ3—2002高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，2002.
