中文摘要：

在不同紧张水平下面的热发电厂的 bunker 海湾的大跨度的对的具体框架结构的地震表演被摇桌子测试调查。A 1/8 microconcrete nonfull 重量可伸缩模型根据原型结构和实验室的条件被设计。三种放大地面运动加速作为地震刺激被采用。白噪音是在通过使用的每个震波的结构的输入。试验性的结果显示结构是安全的忍受在中国代码要求了的七度紧张。结构的自然颤动频率与在很少发生的地震的七度紧张增加地震紧张，在大约 24.5% 的结构减少的自然颤动频率，和结构的僵硬还原剂将近 44% 正在减少。在在一楼的列的顶的损坏是最严重的，结构的弱部分在一楼，并且强壮的 beam/weak 柱现象显然出现，因此这种大跨度的对的具体框架不应该在一个高紧张区域被使用。

英文摘要：

The seismic performances of the large-span prestressed concrete frame structure of bunker bay of thermal power plant under different intensity level was investigated by shaking table tests.A 1/8 microconcrete nonfull weight scaled model was designed according to the prototype structure and the conditions of laboratory.Three kinds of scaled ground motion accelerations were employed as seismic excitations.White noise was input in the structure through each seismic wave applied.The experimental results indicate that the structure is safe to endure seven degree intensity as required in Chinese codes.The natural vibration frequency of the structure is decreasing with the increasing of the seismic intensity,the natural vibration frequency of the structure decreases by about 24.5%,and the structural stiffness reduces by nearly 44% in seven degree intensity of seldom occurred earthquake.The damage at the top of column in the first floor is the most serious,the weak part of the structure is at the first floor,and the strong beam/weak column phenomenon appeared obviously,so this kind of large-span prestressed concrete frame should not be used in a high intensity district.
