摘要

在台风“海葵”和“潭美”分别影响温州期间，对温州某高层建筑进行现场实测，得到建筑第25层楼板结构和停靠在第25层的电梯加速度数据。同时，采用MATLAB软件进行编程，对结构和电梯的动力响应进行了时域和频域特性分析。结果表明：台风作用下，电梯和结构的加速度响应最大值随着平均风速的增大而增大；结构的风致振动传递给电梯，当电梯的固有频率接近结构的前几阶自振频率时，电梯的整体振动响应将表现为对结构振动响应的放大；10min时距内，电梯在水平方向的加速度响应最大值是同层楼板加速度响应最大值的1~1.78倍。最后，以高层建筑现场实测数据为基础，提出了一种计算电梯水平振动响应的简化计算方法，以期为电梯的安全设计和计算提供参考。

Abstract

Field measurement of a high-rise building in Wenzhou has been taken during Typhoon HAIKUI and TRAMI respectively, and the acceleration data of the 25th layer and the elevator stopped at the 25th layer are obtained. Meanwhile, the time domain and frequency domain characteristics of the structure and elevator have been analyzed by MATLAB software programming. Results show that, the maximum acceleration of elevator and structure during typhoon increased with the increase of average wind speed. The wind-induced vibration of structure has transmitted to the elevator, and the overall elevator vibration response is performed by the amplification of the structure vibration response when the elevator inherent frequency close to the first few structure natural frequency. Within 10 minutes, the elevator maximum acceleration is about 1~1.78 times larger than that of the layer. Furthermore, the simplified calculation method for calculating the elevator horizontal vibration response has been put forward based on the high-rise building field measured data, which is expected to provide a reference for the elevator safety design and calculation.
