Abstract: |
A formulation for shear force-slip relationship of shear connector is necessary for more rational design method of steel-concrete hybrid structures. Equations for shear strength of headed stud connector were proposed by many researchers and design codes. However, the equation for shear force-slip relationship which takes account of important factors such as stud diameter has not been proposed. Pushout tests of headed stud connector were carried out under various stud diameter, stud tensile strength, stud height/diameter ratio and concrete strength. Shear force-slip relationship can be represented by one equation with dividing shear force by shear strength and slip by stud diameter although stud diameter is different. The form of shear force-slip relationship curve depends on concrete strength, stud height/diameter ratio and stud strength. An equation was proposed for the enveloped curve of shear force-slip relationship taking these effects into account. |
