Investigation of punching shear behavior of flat slabs with different types and arrangements of shear reinforcement

PROPOSED CORRECTION FACTORS for PUNCHING SHEAR CAPACITY of RC FLAT SLABS with SHEAR REINFORCEMENT

“…Tareshet al [18] used steel angle plates and concluded that the results of ACI-318-19 [2] were underestimated and safe.Schmidtet al [19] used stirrups and concluded that Eurocode 2 [4] depended on concrete contribution and shear reinforcement but FIB Model Code 2010 [10] depended on concrete and steel contribution together.Deifalla [20] used GFRP,CFRP and concluded that calculations of CSA [21] design code were more accurate than JSCE-2010 [8], ACI318-19 [2] codes and safety factor of JSCE-2010 code [8] was safer than CSA [21] and ACI318-19 [2] codes. Shataratand Salman [22] used rectangular and circular spiral stirrups and concluded that Eurocode 2 [4] and ACI 318-19 code [2] were conservative but the predictions of Eurocode 2 [4] were more estimated than ACI 318-19 code [2].…”
