Stress in a section of axial tension member shall not exceed design strength R_y of selected steel multiplied by coefficient of service conditions γ_c (KY and KZ), table 6 of SNiP 2.01.07.- 81*. Slenderness of tension member (CMM) shall not exceed slenderness limit indicated in table 20 of SNiP 2.01.07.- 81* (default value λ_u = 200, but another value can be defined). Net section factor (ratio A_net/A_gross (NSF)) is used for tension member to allow for reduction of design cross-section area.
