Abstract
In order to analyze the static properties of prefabricated composite beam end embedded channel steel joints,the failure mode,bear-ing capacity,stiffness and strain variation of embedded channel steel joints were simulated by static test.The results show that when the thick-ness of the channel steel increases from 100 mm to 300 mm,the maximum bending moment of the specimen increases by 201.9%and the ini-tial stiffness increases by 92.9%.The maximum bending moment decreases when the embedded depth of the channel steel is reduced,the dis-tance between the stirrup is reduced,the cross-hollow cavity is added,the channel steel has no eccentricity and the thickness of the channel steel is reduced.When the embedment depth of the channel steel increases,the distance between the stirrup decreases,there is no span cavi-ty,the eccentricity of the channel steel exists,and the thickness of the channel steel increases,the initial stiffness of the specimen increases.The stiffness of embedded channel steel joints of prefabricated composite beams decreases with the decrease of web thickness.关键词
