RC牆容量曲線分析方法與含RC牆建築物耐震能力評估方法之探討

A study of the capacity curve of RC wall and the seismic evaluation of a building with RC walls

指導教授 : 林炳昌

摘要


RC牆勁度及強度極大,為良好的系統補強構件,能有效提升建築物耐震能力,但是如何以數值模式模擬其非線性行為,雖然已有許多人從事研究,但尚未有良好的定論。ETABS為國內工程界所熟知的分析結構物程式,但是ETABS程式在非線性分析時,並未設定RC牆模擬方式,因此ㄧ般以寬扁柱模擬之(以M3或V2形式模擬塑鉸性質)。本文引用成功大學對於RC牆容量曲線分析後所推導之非線性塑鉸特性,並比較ATC-40和Eurocode 8對於RC牆的剪力塑鉸性質和彎矩塑鉸設定,由ETABS的非線性分析方法驗證近年參予國內RC牆實體試驗成果,希望能確認一個較合理的數值分析模式,以方便國內工程師採用。

RC wall is a good rehabilitation component system for concrete buildings. It improved buildings with stiffness and strength and enhances seismic capacity of building. Although the nonlinear simulate models was investigated by scholars, the numerical simulation of RC wall hasn’t had a better conclusion yet. The computer program of ETABS is one of the well-known programs to analysis a structure and known by the engineers, but hasn’t discuss the simulate methods of RC wall. Therefore, equivalent columns are usually acceptable for modeling walls, (and using M3 or V2 to model the plastic-hinge). Thus, this paper based the capacity curve of RC wall of the National Cheng Kung University model, and compared ATC-40 with Eurocode 8 to infer properties of shear plastic-hinge and moment plastic-hinge of RC wall. Finally, verified with the results of several domestic RC frames tests by using the nonlinear analysis of ETABS. It is expected hopes to provide a reasonable numerical analysis method and a convenient model for engineers to apply.
