Formulating a design for a screw-type shear connector in a compo-site section
Screws-type shear connectors have been most used in Colombia during the last decade; however, an expression for their design in composite sections has only recently been presented (NSR10, paragraph F.2.9.8.2.2). This paper outlines shear design formulation development for screw connectors, analysing the influence of different composite section behaviour parameters. This research studied 18 composite section models using two 42MPa concrete slabs having different arrangements of 1/2", 5/8" or 3/4" diameter 1, 2 or 3 screw shear connectors and 0.08m, 0.12m or 0.14m spacing between connectors. Three specimens were tested by push-out for each model. The laboratory results using the methodology proposed by Ollgaard revealed connector diameter and spacing influence on the model’s behaviour. A design formulation for screws in composite sections is presented.
