Outline of Final Research Achievements

In order to estimate residual bearing capacity of steel frame structure against an aftershock, shake table tests and the detailed three-dimensional finite element analysis using solid elements for the one-third scale model were conducted.
For the preparation of the numerical analysis, I performed a basic study on analytical condition to maintain the accuracy and developed the program to construct the detailed model in a simple manner. The analytical model constructed by using the developed program was utilized to make the experimental design. Finally, the shake table test was conducted. As a result, experimental data useful for the validation of the numerical analysis was obtained. It is planned to reinforce the specimen and perform the additional experiment to reproduce the damage and confirm the difference of the response with and without damage.
