| Research Abstract |
The final target of this study is to analyze the response of a reinforced concrete (R/C) structure to three directional ground motion due to a strong earthquake, and to establish the reasonable earthquake resistant design method of R/C buildings.
This research has presented the experimental date about restoring force characteristics of R/C structural members Subjected to multi-axial load Concerning with a column, tri-axial load means vertical axial force and horizontal bi-axial shearing forces.
This research shows the macroscopic non-linear multi-axial restoring force characteristic model of R/C structures. The macroscopic model is formulated using the theory of plasticity.
Response analysis of R/C structures to three-directional earthquake ground motion was carried out in this project. Some different restoring force characteristic models were postulated in the earthquake response analysis Flexural failure type model, shear failure type model, and others were postulated.
In this project, one additional theme was dealt with. That is high-speed flying object impact problem of R/C walls.
