Abstract: | This paper develops analytical expressions and numerical for reducing the structural matrices which are used in the Force Method of structural analysis. Two simple examples illustrate the calculations for pin-jointed trusses. Two advanced applications, a beam cross consisting of two coplanar beams which are linked by a shear connector, and an equilibrium linear-stress finite element, are also presented. |
