| 摘要： | ACI 318-14 permits no shear reinforcement in prestressed concrete hollow-core units less than 12.5 in. (320 mm) deep. However, due to the difficulty of placing shear reinforcement in hollow-core slabs, the only effective practice is to increase the depth of the section when shear demand exceeds calculated capacity. One promising method of protecting concrete members from brittle shear failure is the use of steel-fiber-reinforced concrete. An investigation of 18 in. (460 mm) deep steel-fiber-reinforced hollow-core slabs showed that ultimate shear strengths were approximately twice those predicted by ACI 318-14. Steel-fiber-reinforced concrete is more efficient in hollow-core slabs than in typical beams due to a preferential fiber orientation in thin webs that enhance fiber bridging efficiency. |
