Review on research progress of metal-plate-connected wood joints

The problem of metal-plate-connected wood joints is an important aspect of wood structure design and research. Metal-plate-connection (MPC), tenon-mortise connection and pin connection are the three most common connection forms in timber structures. The mechanical properties and safety of joint connections in wood structures are of great value to evaluate the performance of building components and structures. The wood is anisotropic and its mechanical properties are susceptible to external factors (e.g., moisture content, density, temperature and load condition). Based on summarizing these influences on the mechanical properties of metal-plate-connected wood joints, this paper further explores the simulation model and analysis software for predicting the performance of these joints, and it also involves aspects of conservatory and creep. Finally, the new development of MPCs is put forward.
