钢-混凝土组合箱梁的抗弯疲劳性能试验研究
Experimental research on fatigue behavior of steel -concrete co mposite box girder
摘要
Abstract
The static and fatigue behavior of three steel and concrete composite box griders were studied by ex-periments.The influence of degree of shear connection on fatigue behavior of steel and concrete composite box girder was investigated.The test results indicate that the relative slip between steel girder and concrete slab would increase because of the repeated loading,which resulted in decrease in sectional stiffness of composite beams.The composite beams behave linearly before fatigue failure.This phenomena indicates that the composite box girder with partial degree of shear connection possesses good fatigue behavior.The larger the degree of shear connection,the better the fatigue behavior of steel -concrete box girder.关键词
