[摘要]對(duì)保溫結(jié)構(gòu)新體系——?;⒅楸貕δ?fù)合剪力墻體系中的高剪跨比剪力墻進(jìn)行低周往復(fù)荷載試驗(yàn)研究。通過(guò)對(duì)比試驗(yàn)的方法,研究了保溫墻模復(fù)合剪力墻與普通實(shí)體剪力墻在承載力、剛度、延性等方面的性能。試驗(yàn)結(jié)果表明:復(fù)合剪力墻的承載力較普通剪力墻的僅降低約7%,而剛度卻明顯減小,既使結(jié)構(gòu)有較高的安全儲(chǔ)備,又使延性得到明顯改善,該體系在結(jié)構(gòu)抗震方面能發(fā)揮較大潛力;墻模與內(nèi)部混凝土的粘結(jié)能力強(qiáng),共同工作性能良好。研究成果可以作為保溫墻模復(fù)合剪力墻工作性能評(píng)價(jià)與工程設(shè)計(jì)的理論依據(jù)。

Abstract:A low-cyclic load test was carried out on large shear span ratio composite shear wall structures with heat preservation formwork by glazed hollow bead (GHB), which is a kind of new insulation structure system. The test was conducted to compare the performance of composite shear wall and ordinary solid concrete shear wall in terms of bearing capacity, stiffness and ductility. Results show that compared with ordinary solid concrete shear wall, the stiffness of composite shear wall reduces significantly while the bearing capacity reduces about 7%. Composite shear wall is characterized by higher safety reserve and significantly better ductility, which indicates this composite shear wall has greater performance in seismic design. The test results also demonstrate that the formwork of composite shear wall works together with internal concrete as a whole. Study results can be applied in design and performance evaluation of composite shear wall structure with heat preservation formwork.
Keywords:large shear span ratio composite shear wall; lowcyclic load test; bearing capacity; stiffness; ductility
