文摘

Shear strength of the slabs supported by the rectangular column was investigated. Punching-shear tests were performed under uneven shear transfer in two directions. Uneven shear transfer significantly affects the resistance of shear reinforcement. Slab shear strength was significantly enhanced by the bar trusses. It is recommended to place bar trusses radially under uneven punching shear.
