RC翼牆構造物之耐震能力分析
The Seismic Evaluation of Buildings With RC wing walls
摘要
現今建築結構補強工法持續的進步，剪力牆補強、磚牆補強、擴柱補強、翼牆補強等等，都是為了加強因地震力損傷建築的耐震能力，其中RC翼牆補強可提供極大的勁度及強度並且較剪力牆補牆節省空間與材料，為良好的系統補強構件，能有效提升建築物耐震能力。如何以數值模式模擬其非線性行為為本文中首要任務，雖然已有許多人從事研究理論的研究與試驗，尚未有良好的定論。Etabs 之非線性分析功能已漸為國內工程界先進所熟知，但是Etabs 之非線性分析時，並未設定RC翼牆模擬方式，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翼牆視為等值斜撐，並與國內規範求得之混凝土極限抗剪力作比較，推導其非線性塑鉸特性，利用Etabs的非線性分析能力驗證近年國內的RC翼牆實體試驗成果，希望能確認一個較合理的方式與數值分析模式，以方便國內工程師採用。

The methods of reinforce building continues to progress, method of shear wall reinforce, brick wall reinforce, extended-column reinforce, RC wing wall reinforce etc., in order to strengthen bears shakes the ability of construction is destroyed which by the earthquake. RC wing wall improved buildings with stiffness and strength and economized on space. It is a good rehabilitation component system for concrete building. Although the nonlinear simulate models have been investigated by scholars, the numerical simulation of RC wing wall has not had a better conclusion yet. The nonlinear analysis of Etabs can't simulate the behavior of RC wing wall. In general, an equivalent column with M3,PMM or V2 is usually used to model walls. Therefore, this paper cites the Softened Strut-and-Tie model to infer properties of shear plastic-hinge of RC wing wall, and verified with large scale of RC frame test, I hope to provide a reasonable analysis method and a convenient model for engineers to apply.
