This study carried out a series of seismic tests to elucidate the difference of movements between two buildings with or without masonry infilled wall in reinforced concrete frames which have no quake proof plan. Both of the experimental buildings showed irreversible deformity at low drift ratio of 0.6%. The strength and stiffness of the building with masonry infilled wall were higher than those of the building without masonry infilled wall, while the ductility of the former being lower than that of the latter. Thus it led to more brittle tendency of the former.

The current seismic design code prescribes structural wall should be designed as special shear wall when building height is more than 60m and seismic design category D. The design code for the irregular wall is not provided. Therefore, the special wall with flange is designed as linear section wall. The ultimate strain of concrete in non-rectangular section would be different form that in rectangular section, then the equation of discrimination for special wall would changed. In the study, nonlinear analysis for linear and irregular wall are performed, and concrete ultimate strain is compared.

To evaluate the displacement dependency of metallic damper which has straight type steel strut, cyclic tests are conducted with the target displacement variables on constant velocity. Form this, width to height ratio of strut is 0.079. From the strength and energy dissipation capacity comparison, cyclic test results are short of the static test results. Therefore more detailed design which are considering target structure period and dynamic characteristics is needed.

This study proposed immediate estimation method for structural integrity using acceleration responses after earthquake. Generally, structural damage detection searching for changes in the natural frequencies by acceleration data. However structure’s natural frequency is changed without damage because of various environmental factors. So that reason, we suggested structural safety estimation procedure using various indicators from analyzing acceleration data. This method is not exactly evaluated structural damage, but using this method is simple to make a decision.

Many researches about damage prediction for earthquake have been managed separately in Korea so that it would be managed comprehensively and systematically. Also it is necessary to develop the algorithms of ground for earthquake disaster response system in NEMA. This is a study to improve the reliability for damage estimation. We compared foreign cases to find a development direction which can be applied to the earthquake disaster response system.

In this study, experimental research was carried out to evaluate the structural performance of high strength R/C interior beam-column joints regions, with or without the shear reinforcement. Specimens designed by the interior beam-column joint regions without the shear reinforcement of existing reinforced concrete building showed a unstable mode of failure and an decrease in load-carrying capacity and energy dissipation capacity and ductility ratio.
