| 摘 要： | 从抗倒塌角度出发,提出了柱顶部分滑移钢筋混凝土框架结构的设想。通过对比该框架结构和常规框架结构的设计过程,并分别进行pushover分析,初步比较了二者的经济性以及弹塑性地震响应。研究结果表明:(1)通过滑移释放部分框架柱的柱顶内力,可以在造价略微增加的情况下,使结构具有更好的抗倒塌能力。(2)结构总层数较少时,柱顶部分滑移框架结构的造价增加比例相对更小。

| Abstract: | A new kind of RC frame structures with sliding at partial column upper ends is proposed in this paper.The design procedures of the new and the ordinary frame structures are compared,and the pushover analyses are carried out for the new and the ordinary frame structures.Simulation results show that:(1) although the construction cost of the new frame structures is a little higher than that of the ordinary frame structures,the property for preventing collapse of the former is better than that of the latter;and(2) the increase of the construction cost of the low-rise new frame structures is limited. |
