DOI: 10.1016/j.apor.2021.102804
Abstract: Abstract The mechanical behavior of the hinged-girder floating bridge is elusive, because the main girder will produce elastic deformation induced by moving loads, as well as movement owing to the action of pier pontoons. Each… read more here.

DOI: 10.1016/j.jcsr.2017.12.007
Abstract: Abstract Applying prestressing techniques increases the load carrying capacity of girders, leading to substantial saving in construction material. In addition, prestressing a steel girder reduces its deflection under external loads, and thus, enhances its flexural… read more here.
