广州南航大厦模型地震模拟振动台试验研究

摘要

Shaking table tests? were carried out for the micro-concrete? m odel of the China Southern Airlines Buil ding in Guangzhou City with the scale of? 1／25．The dynamic characteristics and th e responses of accleration，displacement? and strain of the model under earthquake? of different intensity are studied．Base d on the experimental results，the earthq uake responses of the prototype structur e are estimated by the theory of similit ude．The weak positions of the structure? are found according to the failure situa tion of the model．Some advice is propose d to improve the seismic design of the structure．%进行了广州南航大厦1∶25比例的微粒混凝土整体模型的地震模拟振动台试验,研究了模型的动力特性,以及模型在遭受不同大小地震作用下的加速度、位移和应变反应,并根据模型试验的结果按相似理论推出原型结构在地震作用下的反应,由模型的破坏情况找出结构的薄弱部位,并对抗震设计提供了改进意见。
