摘　　要：结合一项既有住宅增设电梯工程实例,采用Midas/Gen有限元软件,分析了地震作用下电梯井道结构对既有多层砖混结构自振特性的影响及两者连接位置处相互作用力随楼层高度的变化趋势,并讨论了不同连接方式对既有结构及电梯井道结构的地震响应的影响。分析结果表明,不同连接方式时,增设电梯对既有结构抗震性能的影响均较小,但对电梯井道结构的影响显著。It combines with an existing residential adding elevator project example,the influence of the elevator shaft on the natural vibration characteristics of the existing structure,and the trend of the force at the connection position varies with the floor height under the action of earthquake are analyzed by Midas/Gen finite element software,and the effect of the connection forms on the seismic response of existing structure and the elevator shaft is studied.The result shows that when different connection forms are adopted,the adding elevator structure has little effect on seismic performance of existing structure,but has significant effect on seismic displacement of elevator.
