A study on seismic performance evaluation for mid and large suspended ceilings

大型屋顶建筑的大吊顶在地震中的破坏被反复报道，目前正在对大吊顶的结构性能进行深入的研究。在这项研究中，天花板的一般行为被认为是具有一定的平面刚度的大面板，提出。基于该公式进行了特征值分析和动力响应分析，并结合数值结果讨论了该公式的有效性。

Failure of large ceilings in large roof buildings during earthquakes is repetitively reported and intensive researches are now going in order to investigate the structural behavior of large suspended ceilings. In this study, in which the general behavior of ceilings is regarded as large panels which have somekindsofin-planestiffness, is proposed. Eigenvalue analyses and dynamic response analyses are carried out based on the formulation and validity of the formulation is discussed considering the numerical results.
