摘要: 通過 3 塊保溫復(fù)合鐵尾礦混凝土剪力墻的設(shè)計和互相對比試驗,得出其荷載-應(yīng)變曲線、荷載-位移滯回曲線和荷載-位移骨架曲線以及延性系數(shù)等結(jié)果,判斷該新型保溫復(fù)合剪力墻體系的抗震性能與可行性. 結(jié)果表明:該鐵尾礦混凝土制成的剪力墻比普通混凝土剪力墻的脆性大,抗震性能較弱,而剪力墻的鋼筋布置和模板設(shè)計均滿足條件. 同時,針對此復(fù)合剪力墻體系的設(shè)計與試驗,以期為鐵尾礦混凝土和該新型復(fù)合剪力墻體系的應(yīng)用和推廣提供一定的參考數(shù)據(jù)和價值.

Abstract:Through the design and comparative test of three thermal insulation composite iron tailings concrete shear walls, theload-strain curve, load-displacement hysteretic curve, load-displacement skeleton curve and ductility coefficient were obtained,and the seismic performance and feasibility of the new thermal insulation composite shear wall system were judged. The resultsshow that the shear wall made of iron tailings concrete is more brittle than ordinary concrete shear wall, and its seismicperformance is weaker, while the reinforcement arrangement and formwork design of the shear wall meet the conditions. At thesame time, aiming at the design and test of this composite shear wall system, in order to provide some reference data and valuefor the application and popularization of iron tailings concrete and this new composite shear wall system.
Keywords: iron tailing concrete; seismic performance; new thermal insulation composite shear wall; reinforcementarrangement
