Abstract
ABSTRACT IN this investigation the slope-deflection equations of prismatic beams are modified for analyzing continuous nonprismatic wood beams. Residential floor systems are treated as a series of three span continuous T-beams. Cross-sectional area of the beams was increased over the interior supports. Computer pro-grams were developed to calculate angle of rotation, shear, bending moment and deflection of these beams. A program was also developed for determining span ratios that would result in equal maximum deflections when all three spans were subjected to uniformly distributed loads. Tests were conducted on full-scale floor sections. Theoretical and experimen-tal deflections were not significantly different. Thirty-four percent more timber would be required to provide strength and stiffness equal to the experimental three-span continuous beam.
