홈페이지논문 초록 (Abstract)
In the embedment connection using stud connectors, the structural mechanism of column base-plate connection is generally applied fo r design purpose. However, owing to the differences in restriction on the size of concrete member and stud connection details, it is hard to predict the performance of RC wale-steel beam connection by usi ng only the structural mechanism of column base-plate connection. This paper deals with an evaluation on the rotational characteristic of s tud connection between reinforced concrete wale and steel beam wit h relatively narrow RC element. Eight specimens were made and te sted to study the variation of strength and rotational capacity of the stud connection. Test variables were reinforcement ratio, magnitude of axial load, and shear span-to-depth ratio. Test results showed that deformation of tension zone was restricted with the axial for ce. All specimens with the axial force showed sufficient rotational c apacity exceeding the demand regardless of Lb/db. The beam deflection of the RC wale-steel beam connection can be reduced over 20% of that of simple support by considering the rigidity of the stud connection. © 2012 American Scientific Publishers.
