摘要

根据大型厂房钢筋混凝土主厂房结构“强梁弱柱”的特点,选取1/7比例含有3跨3榀5层框排架子空间模型进行拟动力和伪静力试验,研究了模型结构在水平地震作用下裂缝发展规律、破坏机制、结构的变形及耗能性能等。结果表明,该类结构最终的破坏机构为柱铰模式,耗能性能不理想,主要的薄弱环节在结构的上部变截面处。钢筋混凝土框排架原型厂房能满足7度区设防要求,但抗震裕度不大,在更高烈度区应用该类型结构应慎重。
Major plants have the characters with "strong beam and weak column".Based on pseudo-dynamic and pseudo-static tests 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,as well as the capacity for dissipation of energy are analyzed.The results of experimental study show that the structure failure mode is column side way system and the structure dissipation behavior is poor,the soft stories lie in the upper of the structure.The prototype is satisfied with the demand of seismic design in 7 intensity zones,but the safety margin of the structure is limit.So applying this type of structure in the high intensity zone should be carefull.3 tabs,8 figs,6 refs.
