LATERAL RESTRAINT OF NON-COMPOSITE BEAMS. RESEARCH REPORT
Full-scale laboratory and field testing was performed to determine the restraint to elastic buckling of a steel beam supporting a non-composite concrete deck. In the laboratory testing, a 21-ft S 12 X 31.8 beam was loaded to flange yield without indication of lateral instability. Loads were applied through a 6-in. thick reinforced concrete slab having neither mechanical nor chemical bond to the beam. The theoretical buckling stress for this beam was 23.8 ksi. The field test, performed on the 18.25-ft S 18 X 54.7 stringers of a truss bridge with a non-composite deck, showed that the induced live-load bending was less than 15 percent of the design value. Based on these results it is concluded that lateral buckling of non-composite bridge members is unlikely to occur in service.
