In the Steel Joints add-on, you can determine the initial stiffness Sj,ini according to Eurocode and AISC. This can be done for the selected members with reference to the internal forces N, My, and Mz.
In the Members tab of the input dialog box of the Steel Joints add-on, you can select the desired internal forces via a checkbox. Multiple selection is possible! For these internal forces, the stiffness analysis is carried out with a positive and a negative sign.
Calculation of Initial Stiffness Sj,ini
In the Steel Joints add-on, you can perform precise cuts on plates and structural components using the "Auxiliary Solid" component. Within this component, you can use the shapes of a box, a cylinder, or any cross-section as a guide object.
Go to Explanatory VideoIn the Steel Joints add-on, you can classify the joint stiffness.
In addition to the initial stiffness, the table also shows the limit values for hinged and rigid connections for the selected internal forces N, My, and/or Mz. The resulting classification is then displayed in tables as "hinged", "semi-rigid", or "rigid".
Go to Explanatory VideoIn the Steel Joints add-on, you have this option to consider the preloaded bolts in the calculation of all components.
You can easily activate the prestress using the check box in the bolt parameters, and it has an impact on the stress-strain analysis as well as the stiffness analysis.
Go to Explanatory VideoIn the Member Editor component, you can also select the entire member as the modifying object instead of the individual member plates. This way, you can apply both operations "Notch" and "Chamfer" to several member plates.
