摘要

對於鋼筋混凝土結構物而言，最經濟有效抵禦地震力的構件即為RC牆體，此乃由於RC牆具有極高的勁度及強度，因此當地震力來臨時，極大部分的力量將由牆體吸收，以確保其於梁柱構件的安全性。因此，若能以ETABS軟體針對RC牆體進行非線性推覆分析，預測出RC牆體的力學行為，對於未來建築物耐震評估是相有幫助的。
本研究以軟化壓拉桿的理論為基礎，模擬分析國內外30組單/雙層含RC牆門型構架試體的成果，期望找出模擬RC牆非線性行為的塑鉸參數值，使其易於被國內工程師使用的較合理分析模式。

Abstract

For reinforced concrete structures, RC walls would be the most economic and useful members to resist earthquakes. Because RC walls have very high stiffness and strength, most force of earthquake would be communicated to it, when earthquakes happened. Thus, it would protect safeties of other beams and columns from earthquake. Hence if we can use the processes of nonlinearly pushover analysis to predict that the mechanism behavior of RC walls by ETABS. It will be very helpful for seismic evaluation of old buildings.
This study is based on the theory of Softened Strut-and-Tie Model and the resultants of analysis of 30 groups which are single or two layers specimens of RC frames with RC infills. We hope the parameters of plastic hinges of nonlinear behavior modeling of RC walls. And it is convenient and reasonable analysis modeling for engineers.
