Function
- Specify the lateral torsional buckling data for the lateral torsional buckling.
- Lateral torsional buckling of composite beams is verified using simplified method given in EN 1994-2, 6.4.3.2.
Call
From the main menu, select [Design] tab > [Type : Steel Composite Design] > [Design Input Data] group > [Design Parameters] > [Lateral Torsional Buckling Data]
Input
First, select the members in the model and enter the following data:
Both end parts (I & j) have the same shear connector : Check the box if the lateral torsional buckling data is entered under I tab, an identical data will be automatically entered under J tab.
Lateral Torsional Buckling Data
Distance between the springs (l) : Specify the distance between the springs.
Spring Stiffness: Specify the spring stiffness
Alpha( for k1) : Specify Alpha for K1
Spacing between the parallel beams : Specify Spacing between the parallel beams.
