A truss is considered statically determinate if all of its support reactions and member forces can be calculated using only the equations of static equilibrium . For a planar truss to be statically determinate, the number of members plus the number of support reactions must not exceed the number of joints times 2.
Test covers three categories: Truss is statically determinate: m + r = 2j. If m + r < 2j ← Truss is unstable. If m + r > 2j ← Truss is statically indeterminate. |
