Abstract: The nonlinear finite element analysis of a new slitted shear wall structure with heat preservation formwork was introduced. In which 8 slitted shear walls with different parameters were analyzed under lateral loads. The ANSYS software was used to analyze the seismic characteristics of the new structure model, such as the crack expansion and distribution, strain-stress, stiffness, stiffness degradation and ductility coefficient. The non-linear characteristics of walls with different parameters (viz. shear-span ratio, axial compression ratio, combined columns, reinforcement ratio) as well as the parameter effects on the strength, stiffness and ductility are analyzed.
