How to Define a Beam to Column Eccentricity in RISA-3D & RISA-2D

When you have a deep column, it is necessary to model the beam so that it connects to the face of the column. This results in an eccentricity at the joint. RISA-3D and RISA-2D offer two ways to model this eccentricity.

What Are Physical Members?

Members (beams, columns, braces, etc.) are defined in RISA by an I-Joint and a J-Joint. While you and I see a beam occupying physical space between two columns, most programs see a line between Point I and Point J. This is known as a non-physical member.
