- 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)
- Mattock67
- Lp = 0.05*(ElementLength) + 0.5*(ElementDepth)
- HOver2
- Lp = 0.5*(ElementDepth)
- HOver1
- Lp = 1.0*(ElementDepth)
- Point05L
- Lp = 0.05*(ElementLength)
- Point08L
- Lp = 0.08*(ElementLength)
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.)
