| 摘 要： | 钢筋混凝土框排架是火力发电厂常用的结构体系，选取1／7比例含有三跨三榀五层框排架子空间模型进行拟动力试验，研究了结构在水平地震作用下的受力特点、结构的薄弱环节及薄弱层以及框排架协同工作性能等．研究结果表明：该类结构存在明显的薄弱层，主要的薄弱环节在上部变截面处和异型开动节点处，框排架结构最终为柱铰破坏机制，原型厂房可满足7度设防要求，但在更高烈度地区使用有待研究．

| Abstract: | The frame-bent structure was widely used in thermal power plants.The pseudo-dynamic and pseudo-static tests were performed of 1/7 scale model of R.C.with three bay,three span in the thermal plants,the development regularity of cracks and the failure mechanism of building model.The mechanics of the frame coordination with the bent was analyzed.The result of the experimental study showed that:the structure's soft stories lie in the upper of the structure especially at the column and abnormal joints,with the structure turning into column side-way system.The prototype can meet the demand of seismic design in 7 intensity zones.However the application of this type of structure in the high intensity zone still requires further studies. |
