| Abstract: | The character of diagonal tension cracks,the failure patterns and the shear strength of the super stength concrete beam constrain with web bars were analyzed and the shear strength effected by concrete strength, the stirrup characteristic value and the shear span ratio was researched deeply after the test of eighteen supper stength concrtet beams constrained with web bars effectedby concentrated loads. In terms of the testing outcome, some shear strength equations were researched in order to find whether they are appropriated to the super strength conerete beams constranied with web bars.According to the analysis of testing data regression, the recommended equation of super strength concrete beam constrained with web bars was prefered with is appropriated conditions. |
