| Research Abstract |
An self-centering damper which consists of shape memory alloy and super-plastic alloy are developed to realize non-damaged steel bridge. The detail structure of the damper and its optimum design method is proposed. To confirm the validity of proposed structure, the experiment by using damper specimen is carried out. Then, it is confirmed that the damper is able to recover the residual displacement of the 2-span steel bridge after seismic excitation by the numerical analysis with structural optimization.
