胶合木与钢筋桁架混凝土板界面连接抗剪性能试验研究
Experimental study on the shear behavior of interfacial connections between glulam and concrete slabs with rebar truss decks
摘要
Abstract
To improve the precast ratio of components,this article proposed a novel composite structure,the timber-concrete composite(TCC)beam with rebar truss decks,by introducing rebar truss decks into traditional TCC beams.Based on the commonly used screw,notch-screw,and steel plate embedment connections in TCC beams,the shear performance of timber-concrete interfacial connections with rebar truss decks was studied through push-out tests.The shear performance of timber-concrete interfacial connections with ordinary reinforcement bars was also tested for comparisons.The push-out test results showed that,under different connection types,the shear strength and slip stiffness of the interfacial connections in the novel composite beam were significantly improved compared to the push-out specimens with ordinary reinforcement bars,due to the application of rebar truss decks.The novel composite beam presented in this article not only improved the industrialization level of components and construction efficiency but also greatly enhanced the shear performance of interfacial connections,facilitating the application of TCC structures in the field of timber structures.关键词
