Section parameters (tension)

An/Ag Ratio

Specifies the coefficient which applies to a tensile force acting on the cable.

This coefficient defines the relationship of the member cross-section area, not considering the bolt or rivet openings (An), to the total cross-section area (Ag).

Reduction coefficient Ct

Net area reduction coefficient, determined according to Section 5.2.5

Material coefficient

Specifies material resistance coefficients γ_a defined according to Section 4.8.2.3 and Table 3.

Additional conditions for round pipes

Use this option to perform calculations on members that have a round section bent biaxially.

Select Pipes - Unidirectional bending to use the vector sum of the moments My and Mz as a resultant moment, in order to treat the member as unidirectionally bent.
