含邊界構材低矮型RC牆之軟化桁架模式分析

A Study On Pushover Analysis of Low Rise Reinforced Concrete Wall Filled Within Frame Structure

指導教授 : 宋裕祺

摘要


本文提出一有效的程序以解決含邊界構材之鋼筋混凝土牆推覆分析(Pushover Analysis)問題。其方法主要是利用力平衡、變形諧合並配合混凝土軟化模式和鋼筋完全彈塑性模式等兩大組成律作為分析之依據。當鋼筋混凝土牆承受水平作用力時,將分別由橫向鋼筋、縱向鋼筋及混凝土等三大元素來共同承擔。各元素之貢獻,可以ㄧ沿著構架對角線方向之等値斜撐予以模擬,並作為後續推覆分析(Pushover Analysis)之依據。為了證實所提方法之準確性及可行性,本研究採用十六座鋼筋混凝土試體的反覆載重試驗數據來進行比對,結果顯示分析值與實驗值頗為吻合。本研究針對含邊界構材鋼筋混凝土牆提供ㄧ不失準確的等值斜撐的估算方法,冀能供為工程師進行結構設計参考之用。

This paper focuses on the pushover analysis of the low-rise reinforced concrete (RC) wall filled within the frame structure. Incorporating with equilibrium and compatibility conditions, the softened model of the concrete as well as the elastoplastic model of the reinforcement was taken into account for the analysis of the contribution of the RC wall, based on the fixed angle softened truss model. Accordingly, the load-deformation relation of the wall subjected to monotonic lateral load can be analyzed through the proposed procedure. In order to simplify the framed wall structural model, the equivalent structural strut simulating the action of the RC wall infilled, based on the relation obtained, was modeled structurally along the diagonal of the frame for the sequential pushover analysis. To testify the accuracy of the proposed approach, the reported results of the cyclic loading test for sixteen specimens of the structure discussed were adopted for necessary investigation. It shows that this study can provide an acceptable result of the pushover analysis for the frame structure infilled with the low-rise RC wall. Furthermore, the simplified model of the equivalent structural strut we proposed might help the engineers do the structural design or evaluation easier.
