| Abstract: | This paper gives a detailed calculation method of concrete crack width and research status of negative moment area of steel-concrete girder by introducing the concept of crack, and gives the corre- sponding calculating formula. It introduced the causes of the cracks in negative moment area and then put forward the control measures from two aspects of the calculation and construction. |
