摘要：
Under the bending-shear condition, the diagonal crack of web will appear in concrete box-girder bridge when principal tensile stress of tensile-shear zone concrete exceeds principal stress limit value. The overall objective of this study is to develop a calculated method for the fatigue behavior of web under bending-shear of concrete box-girder bridge. First, some basic conceptions and calculation methods of concrete fatigue theory are introduced. Next, the time-history curves of bending moment, shear force and principal tensile stress in typical section have been achieved. Then the effects of...
