Effect of Stirrups on the Behavior of Semi-Precast Concrete Slabs

A semi-slab of precast concrete (or half-slab) is a structural system that consists at the bottom half slab and cast in situ top. To avoid traditional formwork minimize slab, this section can function as reduce thickness slabs, which makes their transportation easy. The interface between overtopping effective for system's performance. improve half-slab floor system, it needed to have shear connector (stirrups). Therefore, better understand behavior six full-scale specimens (2×7.5 m) with different shapes stirrups spacing them were constructed study. One specimen was produced no connections served reference specimen, while other employed connect units. tests found distribution type affect performance semi-precast slab. maximum load capacity slabs rectangular or triangular nearly more significant than reaching 136.11 86.11%, respectively. increased by 81.4 % 54.9% when distance connectors reduced from 600 300 mm. Furthermore, could cracking behavior, stiffness, ductility. Doi: 10.28991/CEJ-2022-08-08-09 Full Text: PDF
