Abstract:
When the several members of a building frame are firmly connected to each other at the joints, stresses are set up in the members by live loads on adja-cent members, as well as by loads on the members themselves. Unequal loads on adjacent spans, or equal loads on unequal adjacent spans, or some spans loaded with others not loaded, will greatly affect moments in the spans and will produce moments in intermediate columns. These moments, arising from action of the frame as a whole, are not determined by the usual moment coefficients. This paper furnishes aready method for their approximate determination. It is based on the funda-mental method of slope-deflections. Example problems and diagrams are included.
