[摘要]介紹了超高層鋼骨混凝土結(jié)構(gòu)的設(shè)計(jì)和特點(diǎn),制作了1∶20比例的模型,進(jìn)行了振動(dòng)臺(tái)試驗(yàn)。根據(jù)試驗(yàn)結(jié)果,通過相似關(guān)系得到原型結(jié)構(gòu)在地震作用下的動(dòng)力特性與反應(yīng),隨著地震作用的不斷增強(qiáng),結(jié)構(gòu)的整體剛度不斷遞減,從而確定結(jié)構(gòu)的薄弱部位,為超高層鋼骨混凝土結(jié)構(gòu)合理進(jìn)行結(jié)構(gòu)設(shè)計(jì)提出了參考建議。
[關(guān)鍵詞]超高層建筑;結(jié)構(gòu)設(shè)計(jì);振動(dòng)臺(tái)試驗(yàn);薄弱部位

Abstract:The structure design features of complex high-rise building are introduced. The 1∶20 scale model is tested to simulate the earthquake on shaking table. The dynamic characteristics and response of prototype structure are got by the similitude relationships according to the testing results. And the whole stiffness is descending along with the strengthen of earthquake force, thereby the structural weak areas are confirmed. Some reference advices of structure design are put forward for the complex high-rise building.
Keywords:ultra high-rise building; structure design; shaking table test; weak areas
