... the deflection formula for prestressed concrete hollow slab (closed section beam) based on the Timoshenko theory. Design/methodology/approach (1) The deflection curves of the prestressed concrete hollow slab beam were obtained under a single point force; (2) linear phases of the deflection values, which were...

... 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...
