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,尚未有良好的定論。SAP2000 之非線性分析功能已漸為國內工程界先進所熟知,但是SAP2000 之非線性分析時,並未設定RC牆模擬方式,因此ㄧ般以寬扁柱模擬之,以M3或PMM形式模擬,或以剪力塑鉸的考量與否等形式行之!本文引用壓拉桿模式將RC牆視為等值斜撐,推導其非線性塑鉸特性,利用SAP2000 的非線性分析能力驗證近年國內的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 the building. Although the nonlinear simulate models have been investigated by scholars, the numerical simulation of RC wall hasn’t had a better conclusion yet. The nonlinear analysis of SAP2000 can’t simulate the behavior of RC wall. In general, an equivalent column with M3, PMM or V2 is usually used to model walls. Therefore, this paper cites the Strut-and-Tie model and ATC-40 to infer properties of shear plastic-hinge of RC wall, and verified with large scale of RC frames tests, we hopes to provide a reasonable numerical analysis method and a convenient model for engineers to apply.
