【摘要】 电梯作为高层建筑不可缺少的竖向交通工具,是非常重要的非结构构件。历次地震灾害表明:电梯抗震性能较差,在地震中遭受不同程度的破坏。目前,各国对加强电梯抗震的呼声越来越高,如何提高电梯抗震性能逐渐引起重视。从三个方面系统梳理了国内外关于电梯抗震性能的研究进展:(1)回顾了电梯在以往地震中的破坏情况,归纳总结了电梯地震破坏类型。(2)从数值模拟和试验研究两个方面介绍了电梯抗震性能的研究现状,指出了不足之处。(3)总结了各国关于电梯抗震的设计方法,比较了规范之间的异同。通过梳理电梯抗震性能的研究现状,展望了未来研究方向,以期为提高电梯抗震性能设计水平提供参考。更多还原

【Abstract】 As indispensable vertical transportation tools for high-rise buildings, elevators are very important non-structural components. The seismic performances of elevators are poor in previous earthquakes and they are quite susceptible to earthquake-induced damages. Many countries are calling for strengthening the seismic performance of elevators, hence the improve the seismic performance of elevators has gradually received attention in recent years. The latest research progresses of the seismic performance of elevators are summarized systematically in three aspects: 1) the observed damage of elevators in past earthquakes is reviewed, and the types of damages are summarized; 2) the state of the art of seismic performance research on elevators is introduced in two aspects of numerical simulation and experimental research, and the shortcomings of existing researches are pointed out; and 3) the seismic design methodologies of elevators in different countries are introduced and compared. Through the summary, the current status of seismic performance of elevators is tentatively concluded and the future direction to be studied is pointed out. The summary provides a reference for improving the seismic design level of elevators.更多还原
