The concept of semi-rigid composite connection has been widely researched in the past; however, most of the researches are limited to
composite joints with metal deck ¿ooring and solid concrete slabs. Composite construction incorporating precast concrete hollowcore slabs
(HCU) is a recently developed composite ¿oor system for buildings. The research on the structural behaviour of the semi-rigid composite joints
with HCU is new and without any previous experimental database. In this paper, eight full-scale tests of beam-to-column semi-rigid composite
joints with steel beams and precast hollowcore slabs are reported. The variables are stud spacing, degree of the shear connections, area of the
longitudinal reinforcement and slab thickness. The test set-up and instrumentation is described in detail. The experimental behaviour is analysed
and based on the test data the structural behaviour of these semi-rigid composite joints is discussed. Based on the experimental data, a simpli¿ed
method to predict rotation and moment capacity for this type of composite connection is proposed.
