      <title>PERFORMANCE OF FULL-SPAN PANEL-FORM BRIDGES UNDER REPETITIVE LOADING</title>
      <link>https://trid.trb.org/View/195800</link>
      <description><![CDATA[An experimental program to determine the effects of repetitive loading on the serviceability and strength of composite panel form bridges is described.  Six simply supported bridge decks were tested.  The specimens consisted of three precast, pretensioned panels spanning in the direction of traffic and composite with a cast-in-place topping slab.  Bond between the topping slab and the roughened interface surfaces of the panels provided the only means of shear connection.  Items considered in the study include the topping slab thickness, panel joint type (flat or beveled-edge), and the effect of longitudinal cracks in the topping slab.  The specimens were loaded repetitively with 2 million cycles of design load (HS20-44 axle load with allowance for impact).  The loading arrangement was such that maximum transverse shear and longitudinal bending stresses were produced during each cycle.  Performance was evaluated primarily on the basis of flexural rigidity, differential deflection between panels, and the strength and ductility of the composite system.  Several states have constructed bridges by using precast panels as full-span stay-in-place forms.  Many of these bridges have developed longitudinal cracks in the topping slab over the panel joints.  The study indicates that cracks of this type do not have a detrimental effect on the strength and serviceability of the bridge deck for the expected repetitive loading. (Author)]]></description>
