［摘要］為了研究方鋼管梁與鋼筋混凝土現(xiàn)澆板的一種新型連接方式，即方鋼管梁采用嵌入混凝土板中一部分的連接方式，對嵌入混凝土板中方鋼管上部側(cè)面布置不同剪力連接件的11個新型方鋼管梁-鋼筋混凝土現(xiàn)澆板組合試件的抗剪性能進行了推出試驗，對其中7個試件進行單調(diào)靜力加載推出試驗，對另外4個試件進行低周反復(fù)加載推出試驗。獲得了不同連接方式試件的破壞模式、承載能力及變形能力。試驗結(jié)果表明，相對于常規(guī)連接方式組合梁，除了在方鋼管梁側(cè)向布置小鋼板連接件的試件取得了較好的承載能力以外，其余剪力連接件組合梁的承載能力及變形能力均有所下降。

Abstract:In order to study a new connection shape of square steel tube beam and cast-in-place reinforced concrete slab, namely the connection shape of a part of the square steel tube beams embedded in the reinforced concrete slab, 11 new composite specimens composed of square steel tube beam and cast-in-place reinforced concrete slab with different shear connectors at top sides of the square steel tube beams embedded in the reinforced concrete slab have been tested, among which there are 7 monotonous static load push-out tests and 4 low reversed cyclic loading push-out tests. The failure modes, bearing capacity and deformation capacity of specimens with different connection shapes were obtained. The test results show that, compared with the conventional connection composite beams, the specimens with small steel plate connections arranged laterally in square steel tube beams have achieved good load-bearing capacity, but the bearing capacity and deformation capacity of the other composite beams with shear connectors have decreased.
Keywords:steel-concrete composite beam; shear connector; shear performance
