... strengthening Static load test At present, the common strengthening methods of hollow slab bridges are as follows: bridge deck thickening, sticking, external prestressing, transverse prestressing, structural system modification, beam reduction and rib increment strengthening. Amongst them, steel plates...

... capacity for strengthening existing bridges with prestressed CFRP plates is becoming an important concern for researchers. The paper aims to discuss these issues. Design/methodology/approach Static load tests of in-service prestressed concrete hollow slabs before and after strengthening are conducted...
