WebA beam is a key structural member used in most constructions. As such, the analysis of a beam under loading is of utmost importance. If a beam is supported at two points, and a load is applied anywhere on the beam, the resulting deflection can be mathematically estimated using the bending equation. Such estimation is based on certain assumptions WebSep 25, 2012 · The beam is divided into DOF+1 equal spans and the full 2*DOF x 2*DOF stiffness matrix is constructed (translation & rotation dofs). This is then statically condensed to a DOF x DOF stiffness matrix (just translation DOF). The only required input is DOF. If only DOF is provided, E, I, & L will be randomly selected from a specified range. bart yukonWebTimoshenko, S. Theory of Elasticity. McGraw-Hill Book Co., New York, 1934.
