Enhancing punching shear and post-punching behavior of flat slabs using wire mesh, integrity bars and fibers [PDF]
Scientific ReportsPunching shear failure is a common issue in the connection between flat slabs and reinforced concrete columns. Once failure occurs, a supplementary load-carrying mechanism is necessary to prevent the progressive collapse of the connections.

Progressive Collapse Analysis Of Flat Slab Buildings With Post-Punching Effect [PDF]
مهندسی عمران شریف, 2021 The reinforced concrete flat slab is one of the types of floor systems used to construct residential, office and parking buildings. Because of the direct transfer of floor loads to columns, flat slabs are susceptible to punching failure in slab-column ...

Punching Shear Characterization of Steel Fiber-Reinforced Concrete Flat Slabs
HighTech and Innovation Journal, 2022 Punching shear failure in thin slabs under concentrated loads can cause shear stresses near columns. The use of steel fiber is a practical way to improve a slab-column connection's punching strength and deformation capacity.

Eccentric punching tests on column bases ‐ Influence of column geometry
Structural Concrete, 2022 Experimental investigations on centrically loaded column bases provide the basis for current punching shear design provisions. However, this symmetric loading condition represents an exception in daily engineering practice since usually load ...
