WMIN

Minimum valid reinforcement amount used in the design of axial load + biaxial bending. Default value WMIN = 0.5 (0 £ WMIN < wmax)

 

WMAX

Maximum valid reinforcement amount used in the design of axial load + biaxial bending. Default value WMAX = 2 (wmin < WMAX).

HB

HBSOLVE

0

CivilFEM uses peak resistance curve only. Value by default.

1

CivilFEM uses both peak and post failure resistance curve.
