［摘要］對兩榀鋼木混合墻體進(jìn)行了水平方向的低周往復(fù)加載試驗，兩榀鋼木混合墻體分別采用不同的連接形式：一種是在木剪力墻周邊構(gòu)件上鉆大孔后用釘固定木墊板和木蓋板的普通螺栓連接；另一種是帶長圓孔鋼板的高強螺栓連接。通過試驗和分析，獲得了兩種鋼木混合墻體的破壞模式、荷載-位移關(guān)系、極限承載力、耗能性能及剪力分配情況。研究結(jié)果表明，高強螺栓連接的鋼木混合墻體剛度比普通螺栓連接的鋼木混合墻體剛度更大，且其承載力和耗能能力也較大；但在極限狀態(tài)下，普通螺栓連接的鋼木混合墻體變形能力更強；兩種不同連接的鋼木混合墻體都能保證鋼框架與木剪力墻協(xié)同工作，相比純框架，鋼木混合墻體的極限承載力、耗能性能和變形能力均得到了提高。

Abstract:Two pieces of timber-steel hybrid walls were tested under lateral low-frequency cycling loading. Two pieces of timber-steel hybrid walls adopted different connection modes: one is to drill large holes on the peripheral components of the timber shear wall, and then a nail is used to fix the ordinary bolt connection of the timber pallet and the timber cover plate; the other one is high strength bolt connection of steel plate with slot hole. Through the test and analysis, the failure mode, load-displacement relationship, ultimate bearing capacity, energy dissipation performance and shear distribution of two timber-steel hybrid walls were obtained. The research results show that the stiffness of timber-steel hybrid wall with high strength bolts is greater than that of timber-steel hybrid wall with ordinary bolts, and its bearing capacity and energy dissipation capacity are also larger; but in the ultimate state, timber-steel hybrid wall connected by ordinary bolts have more deformability. Two different connected timber-steel hybrid walls can ensure that the steel frame and the timber shear wall work together. Compared to the bare frame, the ultimate bearing capacity, energy dissipation performance and deformation capability of the timber-steel hybrid wall have been improved.
