ABSTRACT

The severe damage and functionality loss of hospitals resulting from damage to hospital nonstructural components and medical equipment are frequently reported following earthquakes. Thus, there is an increasing need to understand the performance of medical equipment during an earthquake. In the current study, we conducted a series of shaking table tests to evaluate the seismic performance of three different types of freestanding hospital cabinets. Several earthquake inputs and floor finishing materials were considered to investigate seismic responses, including the acceleration, displacement, and rotation of the cabinets. The seismic damage limit states of the hospital cabinets and inside contents were identified based on test results. Moreover, the corresponding seismic fragility curves of the hospital cabinets under different damage states were developed based on experimental data. The developed seismic fragility models of hospital cabinets can be used in the seismic performance assessments and seismic resilience evaluations of hospital buildings.

摘要

地震后，医院的非结构部件和医疗设备的损坏经常导致医院严重损坏和功能丧失。因此，越来越需要了解地震期间医疗设备的性能。在当前的研究中，我们进行了一系列振动台测试，以评估三种不同类型的独立式医院柜的抗震性能。考虑了几种地震输入和地板装饰材料来研究地震响应，包括机柜的加速度、位移和旋转。根据测试结果确定了医院机柜和内部物品的地震破坏极限状态。而且，根据实验数据绘制出不同损伤状态下医院柜体相应的地震易损性曲线。所建立的医院机柜地震易损性模型可用于医院建筑的抗震性能评估和抗震恢复能力评估。
