Proposals for Prediction of Collapse Behavior and Response Reduction

本文旨在研究地震作用下空间结构的动力倒塌行为，提出倒塌行为的预测方法和空间结构的减震方法。首先，通过振动台试验研究了体育馆屋盖中常用的柱面网壳屋盖的动力倒塌性能。其次，尝试用吸能装置控制结构的地震反应，使结构不倒塌。最后，通过振动台试验和数值分析，研究了水平双向地震作用下结构的反应特性。

The purposes of this study are to investigate the dynamic collapse behavior subjected to earthquake motion and to propose the prediction method of collapse behavior and the response reduction method of spatial structure. First, the dynamic collapse behavior of cylindrical lattice shell roofs which are often used for the roof of gymnasiums is examined by shaking table tests. Next, the control of seismic responses by energy absorption device is attempted so that the structures do not collapsed. Lastly, the response behavior subjected to horizontal bi-directional earthquake motions are investigated by carrying out the shaking table tests and numerical analyses.
