Background
The wooden structure building has a history of thousands of years in China, and with the development of science and technology in the building industry, the technical barrier of the wooden structure development is broken, and the wooden structure building becomes more popular. The wood used for the wood building has high strength-weight ratio, renewable materials and environmental protection. The wood structure building has high assembly rate, and the developed wood building meets the assembly and sustainable development requirements of the building industry. In foreign countries, with the development of middle and high-rise wood structures, cross-laminated-timber (cross-laminated-timber) is widely used as a member for resisting lateral loads, i.e., a cross-laminated-wood shear wall. Cross-glued wood is an engineered wood from europe, abbreviated CLT. The size of the CLT is limited by production conditions and transportation, and when used as a structural material, the CLT needs to be assembled by splicing, usually by nailing. When the CLT is used as a wall body, under the action of lateral load, the connecting nail is damaged before a fastener for connecting the wall and the ground, and the bearing capacity and rigidity of a system are reduced rapidly.
The researches on the rigidity, the bearing capacity, the ductility and the like of the orthogonal laminated wood shear wall connected through the energy-consuming connecting pieces in the vertical seams are not reported in China. Therefore, it is very important to design a system which can effectively improve the energy consumption capability of the assembled CLT shear wall and improve the defect of quick reduction of the rigidity after cracking.
