［摘要］對(duì)國(guó)內(nèi)外雙鋼板混凝土組合剪力墻中所設(shè)連接件的種類(lèi)進(jìn)行對(duì)比分析，在總結(jié)各類(lèi)連接件優(yōu)缺點(diǎn)的基礎(chǔ)上，提出兩種不同構(gòu)造形式的新型連接件：L形連接件和C形連接件，并對(duì)四片高剪跨比雙鋼板混凝土組合剪力墻進(jìn)行了低周反復(fù)荷載試驗(yàn)，以考察此兩種連接件對(duì)組合鋼板剪力墻抗震性能的影響。試驗(yàn)結(jié)果表明：L形和C形連接件均能很好保證外包鋼板和混凝土的協(xié)同工作，此新型組合剪力墻具有較高的承載力、較好的延性及耗能能力；在達(dá)到極限荷載之前，墻體鋼板未發(fā)生明顯的局部屈曲變形，組合剪力墻最終均是因端柱屈曲拉裂而破壞；相對(duì)于C形連接件組合墻，L形連接件組合墻加工方便，能很好抑制墻身鋼板的屈曲，但延性與耗能能力略有降低。

Abstract:Based on the comparison of the types of connectors in the double-steel plate concrete combined shear wall at home and abroad, on the basis of summarizing the advantages and disadvantages of various types of connectors, two new types of connectors were proposed, including L-shaped connectors and C-shape connectors. A low-cycle repeated load test was carried out on four high shear-to-span double-steel concrete combined shear walls to investigate the effects of the two connectors on the seismic behavior of the combined  shear wall. The tests show that, the L-shaped connector or C-shaped connector can effectively help to realize the cooperation of exterior steel plates and concrete, and the new composite shear wall has higher bearing capacity, ductility and energy-dissipating capacity; before ultimate load, the steel plates do not have obvious local buckling, while all the specimens finally damaged due to the buckling and tension fracture of end columns. Compared with the combined shear wall with C-shaped connectors, the construction process of composite shear wall with L-shaped connectors was relatively is convenient， and the buckling of  steel plates of the shear wall can be well suppressed, but the ductility and energy consumption capacity are slightly reduced. 

Keywords:double-steel  concrete combined shear wall; new type connector; seismic performance; experimental research
