![]() ![]() Normal stresses and crack width due to service effects are calculated assuming the concrete ineffective in tension. The effects of all components of internal forces may be superimposed and the interaction of N, My, Mz, Vy, Vz, and T can be checked.Īs concerning the EN code assessments, the serviceability conditions are often governing the cross-section design. The cross-section parts effective for the resistance in shear and torsion are automatically defined based on linear elastic shear stress distribution due to unit loads Qz, Qy and Tx. The torsional resistance of a section is calculated based on an equivalent thin-walled closed section. EN design for shear is based on the variable-angle truss model. Intersecting this surface with the relevant internal moment vector M Res gives the user the detailed information on the level of capacity utilization. After the reinforcement area has been calculated or manually specified, the design code checks can be performed according to Eurocode and AASHTO LRFD.įor ULS checks of flexural capacity a 3D interaction surface of the section resistance is calculated. ![]() Once the global effects are calculated and the relevant envelopes have been created the user can perform code dependent design tasks to determine the required reinforcement content. ![]()
