Experimental database of the deformations and stiffness of headed shear studs in solid concrete slabs

The database also includes the elastic slip, slip capacity, and shear stiffness determined from the load-slip curves in accordance with the second generation of Eurocode 4 (prEC4), and the slip capacity and shear stiffness per AISC 360. The prEC4-related variables were determined using the prEC4 stud resistance model and the SRD1 and SRD2 resistance models developed by the present authors, which outperform all existing models.

Statistical parameters of the database variables, their distributions, and correlations are presented and discussed in the article. The dataset provides the basis for identifying the key variables affecting stud deformations and developing models for predicting the load-slip response, elastic slip, slip capacity, and stiffness of headed shear studs in solid concrete slabs. This information is crucial for evaluating the stud ductility and stiffness, which affect the shear force distribution in steel-concrete composite structures and their resistance, stiffness, and ductility.
