| Abstract |
It has been proposed that an evaluation method for post-earthquake seismic capacity of reinforced concrete buildings based on the residual energy dissipation capacity (the residual seismic capacity ratio )in lateral force-displacement curve of structural members. The proposed method was adopted in the Japanese "Damage Level Classification Standard" revised in 2001. The model(Model A) of crack width and the deformation relationship was used to evaluate the residual seismic capacity of structural members in the Standard. This study is conducted to modify the model (Model B) and to evaluate the residual seismic capacity of RC column. Therefore, experimental tests with positive and negative cyclic loading was carried out using RC building column specimen. Parameters used by the experiment are deformability and member proportion. From the test results, the following conclusions were deduced:(1) Model B agrees well with the experimental result(crack width - deformation relationship) than Model A. (2) It is appropriated that the residual seismic capacity of RC buildings damaged by earthquakes is evaluated using the method in the Guideline. |
