Abstract: The application of steel plate wall and mechanical calculation model were discussed. Combining engineering examples, the mechanical property and energy dissipation characteristics of the steel plate wall and steel plate wall frame were studied, it can not only ensure the effective work of the steel plate wall under rare earthquakes, but also ensure the safety of the main body of steel structure by rationally setting up plastic hinges of steel plate wall and beam. The design process of the structural system with steel plate walls was analyzed according to the performance-based seismic levels of small earthquakes that are not bad, moderate earthquakes can be repaired, and rare earthquakes not to fall. The principle of earthquake resistance on the “strong column-weak beam”, “strong shear-weak bending” of steel plate wall connection frames was studied, and the calculation model of steel plate wall frame under rare earthquake was proposed, which improve the design method of structural system with more energy dissipation members such as steel plate shear wall.
