Cross laminated timber(CLT),a new generation of engineered wood-based product,is gaining attention in the North American market,but it has not been introduced and spread in China yet. In the paper,the mechanical properties of CLT are introduced in details,and the production technology,design methods and research progress are summarized as well. What's more,an experimental study on CLT flexible connection in seismic performance is done. The results show that the failure with all fasteners pulled out is disclosed as an ideal ductility failure. Highly nonlinear,stiffness degradation,strength degradation and pinching are illustrated in the hysteresis curves of connection. An excellent connector in ductility and load capacity is presented by test data analysis.
