I'm a young engineer with 2 years experience and am working for an architect whose father is a retired civil engineer who checks my calculations.<br><br>My question is: We have a building with precast hollow-core floor slab bearing on a steel beam. There are five approx. equal beam spans. I designed the beams as cantilever beams using AISC cantilevered beam diagrams(LRFD or ASD, same diagrams, same factors) to find the moments, reactions, and cant. dimensions. The beam splices then carry only shear.<br><br>My bosses dad wants to design the beams as a continuous beam (with cantilevers) over the five spans with moment carrying splices due to the the fact that he patterned the live load to find the maximum controlling moment. <br><br>He is a civil engineer who has only designed bridges, never buildings. <br><br>I guess my question is do I need to pattern the live load if I use the cantilever beam charts? He and I come up with significantly different beam weights. And is it normal or general practice to use a moment carrying splices in this sort of situation? In my short career I have only seen shear splices in buildings.<br><br>Any help is appreciated. I really like this forum. Thanks! Ben
