非構造部材を含めた不整形低層鉄骨建物の地震脆弱性評価と耐震補強

一项合作研究对悬挂天花板体系的抗震性能评估进行了研究。对日本、中国和北美天花板风格的回顾表明，在面板附着物和悬挂构件的刚度方面存在很大差异。日式体系的全尺寸测试和数值模拟表明，该体系具有较高的抗震性能，房间大小的天花板倒塌危险有限。详细分析了系统的损伤模式、阈值和故障容限，重点分析了功能损失和维修成本。主天花板网架与悬挂电气设备和周围墙壁之间的相互作用增加了破坏。这一发现导致了分析模型和设计程序的发展，并增强了弹性。这一发现发表在著名的国际期刊SCI上的三篇论文和一次国际会议上的一篇文章中。结果和提出的模型在相关社区很受欢迎，论文得到了大量引用。

A collaborative research studied the seismic performance evaluation of suspended ceiling systems.The review on the Japanese, Chinese and the north American ceiling style showed a large difference in panel attachent and the stiffness of suspension members.A full-scale testing and numerical simulations of a Japanese style system presented the high seismic resistance of the system,where falling hazard is limited for a room-size ceiling. A damage pattern,threshold and margin to failure were exmined carefully with emphasis on functionality loss and repair cost. The interactions between the main ceiling grid and suspended electric equipment,and the surrounding wall increased damage.This finding leads to the development of an analytical model and the design procedure with enhanced resiliency.These finding are published in a three SCI papers in the prestigious international journal and one article in an international conference.The results and proposed model are well-received in the relevant community and the papers are getting a good number of citations.
