Abstract
This paper reports an experimental study on the mechanical behavior of concrete slabs at the intermediate supports of axially prestressed continuous composite girders.
Static loading tests were carried out on the concrete slab subjected to negative bending in order to grasp the mechanical behavior of the continuous composite girders. Attention is paid to the differences of mechanical behaviors in terms of manufacturing concrete slabs, prestressing and intervals of studs. It turned out from the experimental study that prestressing for concrete slabs plays a key role for reducing cracks due to negative bending.
