| Outline of Final Research Achievements |
In order to develop a safety evaluation methodology for the retrofitted RC buildings using the numerical method which can evaluate their seismic performance accurately, the following three efforts were made; 1. Development of the analytical model being able to incorporate the resistant mechanism of the RC frame retrofitted with steel braces, 2. Experimental validation on the seismic performance of RC frames retrofitted with steel braces and their numerical verification of the analytical models developed, 3. Simulations of the safety evaluation for the RC buildings with steel braces.
All efforts were almost accomplished. As for the items of 2 and 3, the strengthening effect of the structural slits on the RC frames and buildings retrofitted with steel braces were discussed, and the validity of the analytical models, which can simulate a newly identified fracture mode along the interface joints between RC frame and steel brace frame was investigated.
