Abstract:

A profiled steel sheeting-concrete composite bridge deck for medium- and small-span steel plate girder bridges was proposed. Two continuous deck specimens were fabricated and tested to study the failure mode and load capacities subjected to symmetrical load at two mid-span. The mid-span deflection， the strain of concrete and reinforcement， and the distribution of cracks and crack widths at the hogging moment region were obtained and discussed. The two slab specimens are identical except for the position of perfobond connectors： 9.25 m long and 1.5 m wide， the thickness of the profiled steel sheeting is 3 mm， and the depth of concrete is 24 cm. The test results showed that the failure mode of the specimens was flexure； the load capacities of two specimens were 1 128.5 kN and 1 095.7 kN， respectively； the composite slab with perfobond connectors arranged in the crest had greater bending stiffness； the distribution range of concrete cracks due to the hogging moment is about twice the width of up flange of the girder， which should be paid attention to in design. The load capacities of the continuous composite bridge deck calculated by the plastic theory fit well with the experimental results.
