GaussLobattoIntegrationWeights: gives the same hinge length as the force-based beam-column element with 4 integration points:; Lp=0.05*ElementLength

Priestley96: Lp1 = 0.08*(ElementLength)+0.15*(fY_ksi)/(Db);; Lp2 = 0.3*(fY_ksi)*(Db);; Lp = min(Lp1,Lp2)

Berry06: Lp1 = 0.05*(ElementLength) + 0.26*(fY_ksi)*(Db)/(fpc_ksi)^2; Lp2 = 0.25*(ElementLength); Lp = min(Lp1,Lp2)

The following are calculated internally:

ElementLength: individual-element length
fY_ksi: yield strength of the longitudinal reinforcement in the section in ksi (if not specified in section = 60ksi)
Db: diameter of longitudinal reinforcement in the section (if not specified in section = 1.0)
fpc_ksi: nominal compressive strength of concrete in section (if not specified in section = 4.0 ksi)
ElementDepth: depth of cross section (if not specified in section = 0.)
