Static Behavior of Composite Beam according to the Degree of Shear Connection considering the Stud Shear Connection

摘要

In the construction of composite beam, two kinds of materials which have different propertiesrnrequire connector helping each other to behave similarly. For this purpose it's necessary to use thernshear connector which takes a role of bonding both materials. Composite materials can classify thernconnection of both materials as full interaction, and partial interaction. And it is full interaction thatrnable to demonstrate the best efficiency of composite section. In this study, to evaluate the bendingrncapacity of stud, which is popularly used in composite beam, the studs of different dimensions isrninstalled in the each specimens and push-out test was taken for investigating the variation of shearrnstrengths when the degree of shear connection changes. Also to evaluate ultimate loads when therndegree of shear connection changes, three composite beams which have same section and differentrnstud dimensions were manufactured. Compared the results of each experiment with those of thernFinite Element Analysis, the effect of degree of shear connection to the composite beam andrnrelationship between ultimate loads and the variation of degree of shear connection are estimated.
