heal.abstract	An iterative procedure is proposed to simplify the stress analysis of rectangular building space frames under horizontal actions. The procedure involves the solution of two associated equivalent plane frames, along with equations from a previously published work. The equivalent plane frames contain extensible connecting rods, of an axial stiffness 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 plugged into the previously published equations give 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 axial stiffnesses the equivalent plane frames are solved in the next iteration to give new values of the column shear stiffnesses, and so on. The iterative procedure converges to certain limits of the stresses of the equivalent plane frames. These 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. © 1993.	en
