Consider the given truss and connection detail for member CF as shown. Member CF is made of ASTM A992 steel (Fy - 350 MPa; Fu- 450 MPa), rolled as L125 x 125 x 10 shape. The connection is made of three 25-mm diameter bolts, arranged in one row at the centroidal line. The load P applied on the truss nodes is composed of both dead and live loads. Using LRFD specifications, determine the maximum permissible service live load LL (assume 1.2DL + 1.6LL loạc combination governs) (in kN) that can be applied on the truss such that the design of member CF is adequate. Assume all other members and gusset plates are adequately designed. The ratio of service live load to service dead load is 3.0. All truss dimensions are in mm.
