Abstract

An experimental study on five specimens, representative of precast concrete beam-to-column joints, was conducted to investigate the behavior of headed stud connections subjected to combined shear and bending. The variables were the load eccentricity and the headed stud distribution. During each experiment, shear and normal stresses across the steel-to-concrete interface and the resulting horizontal and vertical displacements were continuously monitored. As intended, all specimens failed along the steel-to-concrete interface because of stud yielding or fracturing. The results demonstrate that both variables investigated influence the response of the system and that estimating the correct distribution of shear and bending actions between the studs is a problem that should be further investigated.
