In the previous paper, the author reported the theory of the Chain Construction with Elastic Joints from the result of the experimental study on the Sandwich Curtain Wall. In the classical theory of the rigid frame, a joint and a member of the framework are considered as a point and a line severally. Namely the area of the joint is taken no account of. But the idealization is doubtful for the actual frame, especially for those of the wide flange members or of the lattice members. The joint must be regarded as a structural member which may be deformed as well as a beam or a column. The present paper shows that each of the structural members connected to a joint of the framework, rotates about the joint in proportion to the bending moment acting on the end of the members and the rotation may be caused by the shear deformation of the joint panel. It is assumed that bending deformation of the panel is disregarded and the panel part in joint is enclosed with rigid members whose ends are hinged. The idealized model of the frametwork is defined as follows, each of those members centered at a point each other with torsional member. The result could be applied for practical purposes because the values solved by this theory in several cases are guite appropriate for the other results.
