摘要: 基于两端固定边界条件下预制混合梁的静力受弯试验,研究了此类预制构件在跨中集中荷载作用下的变形性能。采用奇异函数法建立了预制混合梁的挠曲线计算公式,分析了钢梁与混凝土梁抗弯刚度比、长跨比以及高跨比对变形性能的影响。结果表明:各试件考虑剪切变形影响的挠度计算值与试验值吻合较好,与预制混凝土梁相比,剪切变形对预制混合梁变形性能影响更为显著;由剪切变形引起的附加挠度与总挠度比值随长跨比增加呈线性增长趋势,相同长跨比下其比值随高跨比的增加而增大;建议预制混合梁在高跨比大于1/12时考虑剪切变形的影响。

Abstract: The deformation performance of precast hybrid steel-concrete beams with fixed ends under concentrated load at the mid-span was studied based on a static bending test. A formula of deflection curves of precast hybrid steel-concrete beams was proposed by using the singular function method. The influences of the bending stiffness ratio, length-span ratio and depth-span ratio on the deformation performance were analyzed. The results indicate that the calculated deflection values of the specimens considering the shear deformation are in good agreement with the test results. Compared with precast concrete beams, the shear deformation has more significant influence on the deformation performance of precast hybrid steel-concrete beams. The ratio of additional deflection caused by shear deformation to the total deflection increases linearly with the increase of length-span ratio, while at the same length-span ratio, it increases with the increase of the depth-span ratio. It is suggested that the effect of shear deformation should be considered when the depth-span ratio of the precast hybrid steel-concrete beam is greater than 1/12.

Key words: precast hybrid steel-concrete beam, deformation performance, singular function method, bending test, deflection curve
