For example, the diaphragm of the curved T-beam bridge is prefabricated together with the whole of the beam, the lengths of each T-beam are different, and the angles formed by the diaphragm and the central line are also different, which results in that the extension lines of two adjacent T Liang Hengge beams cannot intersect, the phenomenon of dislocation of the diaphragm occurs, and the problem of reduced axial effective bearing capacity of the beam occurs.
Besides, the traditional diaphragm beam (plate) adopts a reinforced concrete structure, and the problems of cracks, steel bar corrosion and bearing capacity reduction are easily caused by the poor crack resistance of the concrete under the long-term action of vehicle load; although the common concrete diaphragm (plate) has relatively simple manufacturing process and low manufacturing cost, the common concrete diaphragm (plate) has the problems of difficult installation, long construction period, high later maintenance cost and the like, and the potential safety hazard after concrete cracking is also great.
