Determine if the slab acts one-way system or two-way system then draw the loading that acts along members. If you think there will be a point load in the form of a reaction coming from abeam/joist just, simply draw the reaction force at the node/joint. The frame is used to support a load of 30 lb/ft².Sketch loading along members CF and HGFE.a = 12 ft and b = 18 ft
