中文摘要 | 本研究目的以柱及桁架元素模擬預測鋼筋混凝土槽縫牆之側向剛度,預測結果和 不同類型槽縫牆試驗結果比較。17個試體試驗以四種不同方式逐次施加水平載重,直到槽縫 牆試體破壞為止。分析結果柱模式單層試體之Pc、Py、Pu值比試驗值略低而雙層試體則略高 ,極限載重之誤差在2.7至9.0%間;桁架模式極限載重之誤差在3.0至7.8%間。由P-△曲線比 較顯示各階段剛度變化規則之預測準確度均相當高。 |
英文摘要 | Two analytical models of lateral stiffness for a fully slitted RC shear wall are presented in this paper. Seventeen specimens divided into three categories, including five one-story walls without boundary columns, eight one-story walls with boundary columns, and four two-story walls with boundary columns are investigated. Four types of lateral loads (monotonic loading, repeated loading, reversed cyclic loading, and random cyclic loading) with or without axial force are applied in this study. The column model and the truss model are employed for analysis. The complarison of analytical and experimental results shows that most of the flexural cracking load, yielding load, and ultimate load for one-story specimens predicted by the column model are lower than those of experimental results. However, most of the predicted values for two-story specimens are higher than those of the experimentals. The errors in the analytical ultimate load are found to be between 2.7% and 9.0% for the column model, and between 3.0% and 7.8% for the truss model. In addition, the comparison of load-deflection curves for both models shows that the predicted lateral stiffness has satisfactory accuracy. |
