Internal Force Calculation for a Continuous Beam

This Demonstration shows a simplified calculation of the internal forces in a continuous beam. Based on the matrix displacement method, the original calculated result leads to the global stiffness matrix, the displacement on each unknown node, the moments on each unit, and so on. This Demonstration is an edited version of the original work, which has a definite beam structure (known units, lengths, and the form of nodes) and a given range of the value of loads. You can choose the load type you want to apply to the beam and then see the how the structure changes with loads and moment distribution.
