細長鋼筋混凝土單一結構牆與耦合結構牆系統於側向荷載作用下之位移抗震設計

Displacement-Based Seismic Design of Slender Reinforced Concrete Single and Coupled-Wall System under Lateral Loads

本文提出了一種細長鋼筋混凝土結構牆系統之雙線性力－位移關係，該關係是通過使用等效單自由度模型和彈性反應譜，求得細長鋼筋混凝土結構牆在橫向荷載作用下的地震反應行為。本文亦提出了分析的步驟，可以分析單一結構牆和耦合牆系統的地震反應行為。此外，從位移協調條件和位移設計概念，獲得了細長鋼筋混凝土結構牆系統的均勻平移。鋼筋混凝土結構牆系統透過單自由度模型的彈性結構頻譜分析得到的屋頂位移，與解析方法得到的屋頂位移非常吻合。本文提出的公式和分析程序，可以有效地估算細長鋼筋混凝土結構牆的地震反應行為，且其所計算結果與實驗結果相當符合。

This paper presents a bilinear force-displacement relationship for a slender reinforced concrete structural wall system. This relationship describes the seismic response behavior of a slender reinforced concrete structural wall under lateral loads by using an equivalent single degree of freedom model and elastic response spectrum. This paper also proposed an analysis procedure that can analyze the seismic response behavior of single and coupled-wall system.In addition, the uniform translation of the slender reinforced concrete structural wall system was obtainedfrom the displacement concordance conditions and displacement design concepts. The roof displacement obtained by the elastic structure spectrum analysis of the single-degree-of-freedom model of the reinforced concrete structural wall system is in good agreement with the roof displacement obtained by the analytical method. The formula and analysis program proposed in this paper can effectively estimate the seismic response behavior of slender reinforced concrete structural walls, and the calculated results are in good agreement with experimental results.
