| 摘 要： | 通过20个混凝土强度为65.3—84.9 MPa的型钢高强混凝土柱在轴力和水平荷载共同作用下的试验,对型钢高强混凝土柱的抗剪性能进行了研究.试验主要考虑剪跨比、轴压比、配箍率和混凝土强度四个参数对构件抗剪性能的影响.由试验得到了水平荷载下型钢高强混凝土柱的破坏形态,分析了剪跨比、轴压比、配箍率和混凝土强度对构件抗剪承载能力的影响,提出了型钢高强混凝土柱抗剪承载能力的计算公式,公式的计算结果与试验结果符合较好.

| Abstract: | Based on the twenty specimens with concrete strength varied from 65.3 MPa to 84.9 MPa subjected to constant axial compression force and horizontal load,the shear performance of steel reinforced high-strength concrete columns is studied.Four factors,that is,shear span ratio,axial compression ratio,stirrup ratio and grade of concrete strength are taken into consideration.Failure patterns of specimens are obtained and the influence of shear span ratio,axial compression ratio,stirrup ratio and grade of concrete strength on shear performance of steel reinforced high-strength columns is analyzed.The calculating formula for shear strength of steel reinforced high-strength columns is presented and calculating results have good agreements with test results. |
