Abstract
A composite deck structure for a bridge, and a bridge structure and a construction method thereof. The composite deck structure includes a top plate (), longitudinal ribs (), and transverse ribs (), the longitudinal ribs () are fixedly connected to the transverse ribs (), and are connected to the diaphragms () by means of the transverse ribs (), and the transverse ribs () are not provided with cutouts for accommodating the longitudinal ribs (). According to the composite deck structure, no cutout is provided on the diaphragms (), and stress generated by the cutouts is reduced; hot-rolled section steel is used for longitudinal ribs () and transverse ribs () instead of welded steel plates, such that welding seams are reduced and fatigue resistance of the composite deck structure is improved.
