- Abstract:
- In order to study the calculation method of shear capacity of high strength concrete without webs, the experimental data on the shear tests of high strength concrete beams without web reinforcement were collected, these data included shear capacity, concrete strength, shear span ratio, effective cross section, tensile longitudinal reinforcement ratio etc. A database of 291 experimental data was established. Three theoretical formulas of shear capacity of concrete beams were reviewed, the formula in Code for Design of Concrete Structures（GB 50010—2010） and the formula in ACI 318-14 and Zsutty equation. The applicability of these 3 formulas in the high strength concrete beams was evaluated by using the measured data in the database. The further study of the formula in GB 50010—2010 was done under different conditions. The parameters in the formula of GB 50010—2010 were revised based on the experimental comparison. The results show that the prediction results of the Zsutty equation are the most accurate, the accuracy of the formula in GB 50010—2010 is better than the formula in ACI 318-14, and the proposed formula is more suitable for the high strength concrete beams without web reinforcement.
