Keywords: beams (supports); cracking (fracturing); deflection; deformation; floors; joists; lightweight aggregate concretes; loads (forces); openings; reinforced concrete; shear strength; stress-strain relationshipss; structural design; tests; web reinforcement
The second phase of a comprehensive investigation is reported. Tests show the effect on strength and behavior of circular web openings in continous lightweight-aggregate concrete joist floors. Principal variables were size, location, reinforcement, and spacing of openings.
