Abstract
The applications of precast concrete in flat slabs are mainly controlled by the construction joint between the slab elements and columns in order to satisfy monolithic action. This thesis introduces a conceptual approach for the construction detail of such joints. An experimental program was conducted for testing the casting joint between two pre-cast cantilever slabs and a rectangular column. At the joints, the slabs’ and columns’ loop reinforcement were arranged in a staggered overlapped manner. Six tested specimens were loaded asymmetrically under bending, in order to study the moment transfer efficiency and the rotational stiffness of the joint from zero load up to failure. Several variables were studied; the slab reinforcement ratio and distribution, the curvature shape of the column loop reinforcement and the arrangement of shear studs.
Nonlinear finite element analyses (FEA) were performed in order to compare their results with those of experiments and indicate the accuracy of experimental work and evaluate the analytical models.
The behaviours of those construction joints, either experimental or analytical, were compared to that of ordinary monolithic flat slab-column joint to evaluate cracking and deformational behaviour at service as well as their ultimate capacities.
Additionally, the structural behaviour of those joints was discussed using Strut and Tie Method (STM) based on stress trajectories gained by FEA. Design Models using STM are introduced, which can be adopted in the design of such joints.
