吊顶是世界范围内现代建筑中普遍存在的非结构特征，在过去的地震中遭受了广泛的破坏。为了解决这一漏洞，建筑规范现在包括规定的设计和安装要求，他们允许振动台测试评估。迄今为止的测试范围很窄，重点是对制造商的专有系统进行认证。因此，测试使用了有限的仪器，几乎没有尝试开发性能状态。为了解决这个问题，已经开发了一个实验和评估程序：a）开发性能状态B）提供一种将实验数据与规范要求相关联的方法c）开发静态实验程序以补充振动台测试，以及d）标准化最低仪器要求。作为一个案例研究，吊顶系统的一个关键组成部分进行了评估，使用拟议的协议和组件是合格的高地震活动性地区使用。
Suspended ceilings, a prevalent nonstructural feature of modern buildings worldwide, have suffered extensive in the past earthquakes. To address this vulnerability, building codes now include prescriptive design and installation requirements and they permit for shake table testing evaluation. The tests to date have had a narrow scope focused certification of manufacturer’s proprietary systems. As such, the tests used limited instrumentation and little attempt was made to develop performance states. To address this issue, an experimental and evaluation program has been developed to: a) develop performance states b) provide a methodology for correlating experimental data to code requirements c) develop static experimental program to complement the shake table tests, and d) standardize the minimum instrumentation requirements. As a case study, a critical component of suspended ceiling system was evaluated using the proposed protocol and the component was qualified for use in regions of high seismicity.
