WebThe truss shown above is INDETERMINATE. Both equilibrium and deformation must be included in the member load analysis. For this indeterminate truss, the compatibility equation for each member elongation is: e = FL/EA = uC cosθ + vC sinθ . Here E, A and L for each member will influence the member loads. Note from the results below, member (1 ... WebThe structure under consideration is statically determinate. Therefore, simple hand calculations can be performed to calculate the reactions and internal forces in the truss members. These results should be almost identical to the finite element results, with the only difference being due to round off errors.
