Ororbia, Maximilian Edward, "Analysis of Statically Indeterminate Trusses for Progressive Collapse Using Graphic Statics and Complexity Metrics" (2017). A simple triangle truss with degree of angle, θ is 60° on every angle (a equilateral) and same member’s length, L on 2 types of support. Basic Truss Element ≡three member triangular truss Simple Trusses – composed of basic truss elements m = 3 + 2(j - 3) = 2j - 3 for a simple truss m ≡total number of members j ≡total number of joints. Solving this equation yields the value of F_AC. Any idea? Now that the external forces on the truss are known, one can solve for the internal forces within the truss. Video 1 on how to solve a truss.
