ㄱ형 perfobond 리브 전단열결재의 정적 강도평가식
Static Strength Evaluation Equations of ㄱType Perfobond Rib Shear Connectors
- 발행 : 2005.05.01
초록
The ㄱ type perfobond rib shear connector is a ㄱ type flat steel plate with a number of holes punched through. This connector can be effectively used in girder with high shear. The ㄱ type perfobond rib shear connector exhibit very stiff behaviour under service load conditions and also had the characteristic of retaining a significant amount of load after the attainment of ultimate capacity. A regression analysis, which is based on a model that takes into account the contributions of concrete dowels formed by the rib holes, the transverse reinforcement, the strength of concrete in front of the rib, and the ㄱ type plate as well as a nonlinear finite element analysis, is used in the derivation. An empirical equation for the design of ㄱ type perfobond rib shear connector is proposed.
