ABSTRACT
ART. 4.1. NON-CONTINTJOUS BEAMS The greatest benefits of reinforced concrete appear in monolithic structures cast-in-situ, where the beams and columns develop continuity, and where ribs and slabs function in unison to give T-beam action. Nevertheless non-continuous beams occur in such cases as single-span bridges or floors supported on masonry walls; and rectangular beams occur as lintols, or members of space-frames. A variety of worked examples of such cases now follow, all based on the theory given in Chapter 3. The calculations are made both by the Elastic method and by the Plastic method, and in order that the results may be directly compared, the following design stresses are used throughout:
Pcb = 1,000 lb/sq. in., #st = 20,000 lb/sq. in., psc = 18,000 lb/sq. in.
