Consider the truss shown with applied dead loads. Suppose a live load, going on the same direction as dead loads, may be applied on one of the lower chord nodal points (L, K, J, I, H), with a value of 15 kips. The members are connected by four 7/8-inch diameter bolts in a single row parallel to the longitudinal axis of the member. The members are required to have a thickness of 3/4 inches and should be made of ASTM A36 steel (Fy = 36 ksi: Fu = 58 ksi). Assume that the bolts and the gusset plates are adequately designed. (a) Determine the dead load tensile force on member BK (b) Draw the live load influence diagram for the bar acting on member BK. Determine the point of application of the live load that would produce maximum tension on member BK. Determine also the maximum live load tensile force on member BK.
