Experimental Study of Interior Slab-Column Connections Subjected to Vertical Shear and Cyclic Moment Transfer

摘要

An experimental investigation was conducted to study the seismic behavior of slab-column connections under vertical shear and cyclic lateral load. Test variables include gravity shear ratio (V_g/V_0) and flexural reinforcement ratio (ρ) of slab within an effective slab width between lines that are one and one-half slab thickness (c_2 + 3h). The strength and ductility of the test specimens were evaluated in accordance with gravity shear ratios and slab reinforcement ratios. The shear strength of the test slabs was compared with the predictions by ACI 318-05.
