The researchers developed a new type of steel girder by combining hot-rolled H beams with high-strength steel plates. They prestressed the girder by releasing the beams' stresses, making it stronger. Tests showed the girder can handle more weight and have longer spans than regular girders. This innovation could lead to more efficient and effective temporary bridges.
