| Research Abstract |
Horizontally mixed structural system was suggested to retrofit the existing old R/C buildings. In this project, the following experimental and analytical studies are conducted, (1) the development of connection joint technique by use of post installed anchor bolts, and (2) an evaluation of inelastic response behavior for multi story retrofitted buiding structure.
The first, the specific and actual connection joint method between R/C and extended steel member is proposed. And the horizontally loading tests are conducted on test specimen with proposed connection joint. From the test results, the resistant mechanism and ultimate states of this joint are clarified. Furthermore, the FE analysis is conducted to investigate the test result in detail, and to propose the analytical model and design criteria.
The next, the inelastic response analysis on multi story retrofitted building structural model is conducted. From the analysis results, the ultimate seismic response behavior are clarified.
