Response of a R/C Structure to Three Dirsctional Earthquake Ground Motion

本文的最终目的是分析钢筋混凝土结构在三向地震作用下的反应，建立合理的钢筋混凝土结构抗震设计方法。三轴荷载是指竖向轴力和水平双向剪力，研究了钢筋混凝土结构的宏观非线性多轴恢复力特性模型。采用塑性理论建立了宏观模型，对该工程的钢筋混凝土结构进行了三向地震反应分析。在地震反应分析中假设了不同的恢复力特性模型，包括弯曲破坏型模型、剪切破坏型模型等。这就是高速飞行物撞击R/C墙的问题。

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.
