Consider the warren truss below, assume all members are pin connected and use W8x13 for member section. The span of truss is 6x12 ft and the height is 16 ft. The truss is subjected to point loads of 20 kips @node B, C, D,E and F. H B C E Use the virtual work mcthod to calculate vertical deflection of node B, C and D.I
