摘要

開口RC牆的存在將主控結構物行為，國內現行規範規定建築物設計時須將牆體納入結構計算，因此有必要對於構架含開口RC牆之耐震行為加以探討，確定其力學行為、破壞模式與分析模式，才能有效的加以分析、設計、補強或修復。本研究之目的為含開口RC牆構架載重位移曲線之預測，包含完整曲線、極限強度、位移以及勁度等。本研究建議一個開口RC牆構架載重位移曲線預測方法，以國家地震工程研究中心所作之開口RC牆構架試驗數據進行評估，並將預測結果與文獻之試驗結果做分析比較，結果顯示本研究建議之開口RC牆構架載重位移曲線預測方法之預測結果合理。

RC wall with openings is the building behavior controlling element during earthquake. The earthquake resistance Code requires that RC wall need to be included in the earthquake resistance calculation of structure. Therefore, exploration of the earthquake resistance behavior of RC wall with openings and establishment of its mechanical behavior, failure model and analytical model are necessary in order to make effective design, reinforcement and repair of RC building possible. The purpose of this research is to establish the load-deflection curve including the entire curve, ultimate strength, displacement and stiffness of the RC wall with openings. In this research a load-deflection prediction method of RC wall with openings was proposed and test data of six RC walls with openings from NCREE were used to generate the prediction for comparison. It is indicated from the comparison results that the prediction made by the proposed prediction method is quite reasonable.
