Using Load Type 'End Prestress'
Until now, the load type prestress has always been an initial prestress in the Dlubal Software programs. The defined load magnitude was applied and, depending on the stiffness of the surrounding system, the prestress remained more or less as axial force in the cable.
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
