Abstract |
An efficient design concept for earthquake loads, which is called performance based design, has been standard design in USA, Europe and Japan since those countries experienced severe earthquake damage at end of 90's. For general design, struttie model well predicts the strength of the disturbed region, however, it does not provide ductility information at the failure. Therefore, simple tools which are able to predict both the strength and the ductility of RC structures are in demand. 2D lattice model is introduced in this study as an analysis tool for the RC structures subject to earthquake. Experimental correlation studies indicate the 2D lattice model quite well predict the strength as well as the ductility of RC structures.
