Behaviour of the joint between slabs and walls composed of light steel and foam concrete

Aiming at the prefabricated composite structure, a new type of interior joint in the prefabricated slab wall system suitable for light steel-concrete composite structures is proposed. In the paper, the pseudo-static test of the joint was designed and carried out, and its failure pattern was mainly described. In addition, the test data was analysed from the perspectives of load-displacement curve, strength, stiffness, ductility and energy dissipation. The finite element analysis software ABAQUS was used to carry out finite element modelling and calculation of the new joint, and the results were compared and analysed in terms of failure process and load-displacement curve analysis. The results show that it is feasible to apply the joints in this new type of slab wall system to light steel concrete composite structures.
