| Research Abstract |
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.
