　　In the Japan Tohoku Earthquake, about 500 stadium buildings served as temporary refuges, however, their steel roof joint bolts were damaged.The research is to study damage of connection joints between RC column and steel roof using an overall model and fine model in seismic response under strong earthquake shaking.The joint eiastoplasticity deformation can be considered in this fine model.A retrofit work of this beating supports using rubber blanket is also investigated.Finally, validityof themethodproposedisverifiedthroughcomputer simulation and sitetest.
