Neglect buckling

• The buckling analysis may be switched off with the help of this setting. Following parameters won't be enabled in that case.

Different sector length for buckling

• If the fundamental length for the buckling analysis differs from the sector length l, this check box should be switched on and the fundamental length should be defined in the input field "Length". In other cases, the sector length is considered as a fundamental length for buckling analysis. The sector length is updated automatically after any modification (e.g. insertion of new sector).

Length

• The fundamental length l that is used as an input for the calculation of the buckling length l₀.

Buckling length

• The buckling length in the corresponding direction that is calculated with the help of the fundamental length for buckling analysis and the supporting style of the sector that may be changed in the window "Buckling length" (launched by the button ""). The hinged supporting style is considered as a default, the buckling length is equal to the fundamental length in this case.

Factor

• The coefficient that depends on the distribution of first order moment c₀ has to be specified for the analysis method based on the nominal stiffness according to the chapter 5.8.7.3(2). The coefficient that depends on the curvature distribution c has to be specified for the analysis method based on the nominal curvature according to the chapter 5.8.8.2(4). Recommended values are described in the part "Buckling" of the theoretical help.
