heal.abstract	An iterative procedure is proposed, to simplify the stress analysis of rectangular building space frames, under horizontal action. The procedure involves the solution of two associated equivalent plane frames, along with the use of equations from Rousopoulos, Theory of Elastic Complexes (Elsevier (1965)). The equivalent plane frames contain extensible connecting rods, with axial stiffnesses to be determined, which connect the individual plane subframes that form the given building space frame. The iterative procedure comprises evaluation of the column shear stiffnesses, by solving the equivalent plane frames. The column shear stiffnesses with the equations of the Theory of Elastic Complexes, furnish values of the axial deformations of the connecting rods, which in their turn indicate new values of the axial stiffnesses of the connecting rods. With these new values of the axial stiffnesses, the equivalent plane frames are solved in the process of the next iteration to furnish new values of the column shear stiffnesses, and so on. The iterative procedure converges to certain limits in the stresses of the equivalent plane frames, which limits are equal to the stresses developed in the given building space frame, under the given loading. The convergence of the iterative procedure is discussed. © 1994.	en
