BTII+ | Lateral Torsional Buckling Analysis | Update Information
Graphical view of the results at the cross-section:
At the thin walled profiles not all values could be selected
The point of application for loads in z-direction was set in the origin
The reduction factor Chi, LT is modified according to the moment distribution. (Eq 6.58).
Internal force Vz:
Direction change for the load input at the cross-section fixed.
Design values for support reactions can be transferred to the steel program STS+ as design load cases.
The rotation in the graphics are corrected to the unit [rad].
Graphical output improved.
Correction for the design of lateral and lateral torsional buckling according to EN 1993-1-1, 6.3.4
User defined cross section values corrected.
Output table: Support reactions for cross sections with turned principal axes.
First Version of BTII+ in English with new user interface.
Eurocode with National Annex implemented for Great Britain, Germany and Austria.
