【摘要】 采用四种不同的水平加载模式对多层钢框架结构进行了多遇地震、罕遇地震作用下的Pushover分析,得到结构的顶点位移、各楼层层间位移、层间位移角以及塑性铰分布,在性能点处,多遇地震作用下结构并未出现塑性铰,在罕遇地震作用下结构逐步出现塑性铰,进而判断出结构中的薄弱环节为结构的底层。更多还原

【Abstract】 The paper adopts the four various horizontal loading model on the multi-layer steel frame structure to have the Pushover analysis under the effect of the frequent earthquake and rare serious ones,concludes the top displacement,the layer displacement of all layers,the displacement angles between layers and the distribution of the plastic hinges,and the plastic hinge never occur on the structure’s performance points under the effect of frequent earthquakes,and the plastic hinges gradually appear under the effect of the rare serious earthquakes,so as to judge the weak step is the bottom of the structure.更多还原
