Design of the members subject to axial tension is performed per chapter D of AISC 360-16.
All the cross-section profiles described in section 1A.10 are considered for tension checks.
Eye bars and pin-connected members are not checked per clauses D5 and D6.
The tensile strength is calculated with due consideration to both tensile yielding and tensile rupture effects as per D.2 of the code.
The Fy and Fu values would be chosen based on the grade of steel associated with the member, specified by SGR parameter. Note that the implementation also provides a means to create custom steel grades. If SGR is set to 0 ("custom steel"), then the values assigned for FYLD and FU is used respectively.
The code does not mandate the maximum slenderness limit for members in tension. However, the program will check against a maximum slenderness ratio (L/r) which is specified using TMAIN parameter. The length considered to calculate the tension slenderness will be the full member length.
Effective Net Area
The gross area, Ag , and net area, An , of tension members shall be determined in accordance with the provisions of Section B4.3 of AISC 360-16.
The effective net area is the net area multiplied by the parameter SLF (shear lag factor).
The net area is the gross area multiplied by the parameter NSF (net section factor).
