| The bending behavior of nine reinforced concrete beams with 500MPasteel bar were tested and studied in this paper.a test with nine reinforced concrete beams was carriedout,The bending capacity and crack spacing and width at service loads were analyzed,The deflection characteristics of this beams and the effect of some factors on it were investigated through experiment and analyses.As the same time,the bending capacity,deformation and crack width of two groups of the members with welded wire fabric near the concrete surface were compared. The test results indicate that the members with 500MPasteel bar can work as well as the common RC flexural members,and the formula in Code for Design of Concrete structures can be used to calculate bending capacity and crack width of the members,but the calculated crack width should be calibrated.Furthe-rmore,welded wire fabric can be used to control the development of crack and make the beams meet the limit of the maximum crack width.This paper found finite element model to stimulate the testing process,also comparesthe testing results with finite element analysis results. |
