| Abstract: | Based on design calculation and experiment with actual load acting on home position of concrete frame beam with 500MPa class reinforcing bar,concrete crack width is studied.Three results had been compared,including the concrete crack width experimental values,the design calculate values of Code for Design of Concrete Structures and its modify results.A new calculation method is proposed to configure 500MPa class reinforcing bar. |
