摘要
介绍了超高层钢骨混凝土结构的设计和特点,制作了1∶20比例的模型,进行了振动台试验。根据试验结果,通过相似关系得到原型结构在地震作用下的动力特性与反应,随着地震作用的不断增强,结构的整体刚度不断递减,从而确定结构的薄弱部位,为超高层钢骨混凝土结构合理进行结构设计提出了参考建议。
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.
