As we should know by now, a force has many components to it. When dealing with forces, Newtons third law of motion, explains the process. Our previous reflection on beams, columns, spans, girders, all apply a certain amount of force on one another. Which then applies a combined force to concreted loads. Each column would have its own tributary area where the forces in that area will apply its load on that column. The way in which we design a structure can cause a beam to resist, deflect, buckle, rotate, under tension and/or compression with the dead and live loads applied. There are multiple ways of framing, placing and connecting a beam. There is no one right answer, only under the circumstances that your structure requires a specific type.
