Great variety of calculations
1st and 2nd order analysis
The analysis model is automatically generated based on the completely separated engineering model. The great variety of the possible calculations includes the first and the complete second order (not only P-D effect) analysis. The deformation of each member/surface of the model, the internal forces, the reactions and the necessary data can be illustrated on the 3D model with colors, diagrams, tables, etc.
ConSteel is able to take into account the effect of the connection stiffness of joints created in the csJoint module during the analysis. The exceptionally fast and robust equation solvers yield optimal calculation time even for unusually huge models.
Flexural, torsional and lateral-torsional buckling analysis
Since steel members are usually relatively slender, various modes of global stability failure can occur: flexural buckling, torsional buckling, lateral-torsional buckling or any interactions between them. All modes can be calculated by the 7DOF element (see: Vlasov beam theory). Although it is quite an important and advantageous feature for the stability design of these members, it is essential to consider during the modeling phase that the accurate calculation of all the torsional modes is highly dependent on the 7th warping DOF.
When the plastic analysis is selected in ConSteel, a plastic hinge analysis is performed considering any planar hinges that may be developed on the local y-axis of the cross-section due solely to the major axis bending moment (My) – no other effects (like shear, normal force or minor axis bending) influence the formation of the hinge.
Local buckling analysis built from shell elements
ConSteel includes advanced features for the Local buckling analysis of slender steel members built from shell elements. The user can easily create the 3D model of a structure, defining the mesh of the finite elements by using graphical tools of ConSteel or by 3d model from other software. The local buckling results can be illustrated through tables, diagrams and color palettes on the model.
