Abstract:	Eight ribbed precast reinforced concrete one way slabs with and without trussed shear reinforcement were tested for studying the shear behavior of the ribs (beams). The slabs were submitted to symmetric loading applied from the top. The experimental program consisted of two reference slabs without shear reinforcement; two slabs with a truss as shear reinforcement at the ribs; two slabs with vertical closed stirrups as shear reinforcement at the ribs and two slabs with vertical closed stirrups and a truss as shear reinforcement at the ribs. The slab panels were 1,26 m (width) by 3 m (long) by 15 cm (height), composed with three 9 cm ribs (width) and 4 cm cover, with the voids filled with polystyrene blocks. Results o f deflections, reinforcement and concrete strains, and ultimate loads are compared with the estimations o f codes NBR 6118/78. NBR 6118/03. ACI 318M-02 and with the recommendations of Zsutty [23], referred to shear in reinforced concrete slabs and beams. Results show that the trusses that were utilized allows an increase in resistance of approximately 40% in relation to the reference slabs. but are less efficient than the closed vertical stirrups.
