THE SERVIE LOAD RESPONSE OF SHORT-SPAN SKEW SLAB BRIDGES DESIGNED BY YIELD-LINE THEORY

THE RESULTS FROM TESTS ON SEVEN MODELS OF SHORT-SPAN SKEW SLAB BRIDGES ARE PRESENTED. FOUR OF THE SLABS HAD A SKEW ANGLE OF 45 DEGREES AND THE OTHER THREE OF 30 DEGREES, THE ASPECT RATIO BEING ABOUT 1.0 FOR EACH SLAB. DIFFERENT ARRANGEMENTS OF THE REINFORCEMENT WERE ADOPTED FOR EACH SLAB. BOTH THE LONGITUDINAL AND TRANSVERSE REINFORCEMENT BEING PROPORTIONED IN ACCORDANCE WITH YIELD-LINE THEORY. IT IS CONCLUDED THAT SUCH SLABS ARE UNLIKELY TO SATISFY THE LIMIT STATE OF SERVICEABILITY. IT IS SUGGESTED THAT, IF YIELD-LINE THEORY IS TO BE INCORPORATED INTO THE LIMIT STATE DESIGN OF SUCH BRIDGES, THE LONGITUDINAL STEEL SHOULD BE DESIGNED TO SATISFY THE LIMIT STATE OF SERVICEABILITY UNDER BOTH STANDARD AND ABNORMAL LOADING, AND THAT THE TRANSVERSE STEEL SHOULD THEN BE DESIGNED BY YIELD-LINE THEORY FOR FACTORED ABNORMAL LOADING. /TRRL/
