This paper investigates the seismic performance of a functional traction elevator as part of a full-scale five-story building shake table test program. The test building was subjected to a suite of earthquake input motions of increasing intensity, first while the building was isolated at its base, and subsequently while it was fixed to the shake table platen. In addition, low-amplitude white noise base excitation tests were conducted while the elevator system was placed in three different configurations, namely, by varying the vertical location of its cabin and counterweight, to study the acceleration amplifications of the elevator components due to dynamic excitations. During the earthquake tests, detailed observation of the physical damage and operability of the elevator as well as its measured response are reported. Although the cabin and counterweight sustained large accelerations due to impact during these tests, the use of well-restrained guide shoes demonstrated its effectiveness in preventing the cabin and counterweight from derailment during high-intensity earthquake shaking. However, differential displacements induced by the building imposed undesirable distortion of the elevator components and their surrounding support structure, which caused damage and inoperability of the elevator doors. It is recommended that these aspects be explicitly considered in elevator seismic design.

某五层楼电梯系统的振动台测试

本文研究了功能性牵引电梯的抗震性能，作为全尺寸五层建筑振动台测试程序的一部分。测试建筑物经受一系列强度增加的地震输入运动，首先是将建筑物在其底部隔离，然后将其固定在振动台平台上。此外，还进行了低振幅白噪声基础激励测试，同时将电梯系统放置在三种不同的配置中，即通过改变其轿厢和配重的垂直位置，以研究由于动态激励引起的电梯部件的加速度放大. 在地震试验期间，报告了对电梯的物理损坏和可操作性及其测量响应的详细观察。尽管在这些测试中机舱和配重由于冲击而承受了很大的加速度，但使用良好约束的导靴证明了其在高强度地震中防止机舱和配重脱轨的有效性。然而，由建筑物引起的不同位移使电梯部件及其周围的支撑结构发生不希望的变形，从而导致电梯门损坏和无法操作。建议在电梯抗震设计中明确考虑这些方面。由建筑物引起的不同位移使电梯部件及其周围的支撑结构发生不希望有的变形，从而导致电梯门损坏和无法操作。建议在电梯抗震设计中明确考虑这些方面。由建筑物引起的不同位移使电梯部件及其周围的支撑结构发生不希望有的变形，从而导致电梯门损坏和无法操作。建议在电梯抗震设计中明确考虑这些方面。
