| Abstract: | Based on experiments under short-term and long-term loads,studies on failure patterns,prestressing loss,ultimate stress of tendons,bending capacity,short-term and long-term deflections of new-type prestressed steel-concrete composite beams with prestressed concrete slabs and prestressed steel beams are studied in detail,and the corresponding design suggestions are systematically put forward. |

| Keywords: | new-type prestressed steel-concrete composite beam performance under short-term load performance under long-term loads design |
