Abstract:

Engineering Cementitious Composite (ECC) materials with PolyVinyl Alcohol (PVA) fibers are employed to investigate the effect of the ductile matrix on the behavior of flat plate-column connection. Totally four slabs are cast and tested, three of PVA-ECC slabs are compared to control slab of normal concrete. The thickness of the slabs used was variable (50, 60 and 80 mm) in order to investigate the effect of the size, and keeping the other size is constant (500 × 500 mm). All four slabs are reinforced with same conventional reinforcement ratio. The results showed that in the ductility of the slabs made from PVA-ECC are significantly enhanced compared with the normal concrete slab, this ductility improvement decrease with increasing the slab thickness, and more over the shear stress in the specific location is reducing with increasing the slab thickness
