Abstract
Shear reinforcement can be used to maximize the ductility and strength of the reinforced concrete flat slabs. However to be efficient, the shear reinforcement must be anchored well in the tension and compression zones of the slab. The test results on the slab-column connection models which provided with shear reinforcement are introduced in this research paper. The benefits of using shear reinforcement are to reduce the slab thickness, cost, and weight of the structure. The experimental test program included eight flat slab specimens having average concrete compressive strength 35MPa except two specimens (S₂ & S₄) have compressive strength (25 & 45MPa) respectively. The slab specimens were 1100*1100mm and 120mm thickness with bottom and top reinforcement (RFT) 10Ø16/m in both directions (high grade steel) except specimen (S₅) was 1100*1100mm and 140mm thickness with the same slab reinforcement. The slabs were divided into three types; the first type had no shear reinforcement and consider the control slab (S1), the second type (S₂₋₅ & S₇) had shear reinforcement of vertical stirrups at a distance of d/2 from the column face (loaded area), and the third type (S₆ & S₈) had vertical stirrups at a distance of 1.5d from the column face. The eight specimens were loaded with a concentrated load at the mid span until failure
