R-UHPC梁抗剪承载力有限元分析
Finite Element Analysis of Shear Capacity of R-UHPC Beam
摘要: 为研究配筋超高性能混凝土(R-UHPC)梁的抗剪性能，结合6根不同钢纤维掺量和配箍率的R-UHPC梁受剪破坏试验，通过有限元参数分析，验证了极限荷载、纵筋应变、箍筋应变、开裂情况，得出剪跨比为1.2~2.8范围的R-UHPC梁抗剪承载力及变化规律。
Abstract:
In order to study the shear behavior of R-UHPC beams with reinforcements, combined with shear failure tests of 6 R-UHPC beams with different steel fiber content and reinforcement ratio, the ultimate load, longitudinal bar strain, stirrup strain and cracking were verified by finite element parameter analysis, and the shear bearing capacity and variation rule of R-UHPC beams with shear span ratio of 1.2~2.8 were obtained.
