description The invention relates to a fabricated steel-concrete composite beam and a construction method thereof. An existing assembly type steel-concrete composite beam structure is difficult to meet the use requirement of a large-span mixed type bridge. The cross section of the fabricated steel-concrete composite beam is in a P shape, and the fabricated steel-concrete composite beam comprises a steel beam section, a steel-concrete composite section and a concrete section which are sequentially connected in the longitudinal direction; transverse prestressed steel strands are distributed in the steel-concrete combined section and the concrete section, and the ends of the prestressed steel strands are anchored in the steel beam section. Factory prefabrication and prefabricated construction are adopted, the requirement for quality control is met, the influence of factors such as the environment on the beam section quality is reduced, and the construction progress is accelerated; and the good stress performance of the stee
