Three-dimensional stiffness equations of uniform cross section bar are used so that the monent distribution coefficients for space frame without linear joint displacements are obtained.Hence, the moment distribution method used for plane problems can be used in space structures.The method is simple for calculation and it is rapidly convergent.It can be used both in engineering for reference and in teaching as a supplement to structure theory.
