beamIntegration('HingeRadauTwo', tag, secI, lpI, secJ, lpJ, secE)
Create a HingeRadauTwo beamIntegration object. Two-point Gauss-Radau integration over each hinge region places an integration point at the element ends and at 2/3 the hinge length inside the element. This approach represents linear curvature distributions exactly; however, the characteristic length for softening plastic hinges is not equal to the assumed plastic hinge length (equals 1/4 of the plastic hinge length).
