Punching Shear in Reinforced Concrete Slabs
Also Known As:
ACI SP-232:2005 is a special publication by the American Concrete Institute (ACI) that focuses on the topic of punching shear in reinforced concrete slabs. Punching shear failure occurs when complex three-dimensional stresses at the slab-column connections exceed the capacity of the concrete, leading to potential structural failure.
The ACI/ASCE Committee 445, Shear and Torsion, organized a symposium on punching shear during the ACI Fall 2005 Convention, which served as the basis for this publication. The aim of this publication is to provide updated developments in the state of the art and research regarding behavior, rational design, and evaluation of code provisions related to punching shear.
The publication is divided into two parts. The first part includes a report co-authored by members of Subcommittee 445-C, which addresses design philosophy, code provisions, contributions of flexural and shear reinforcements, and the effects of seismic and blast loads on punching shear. The second part consists of papers from different research centers around the world, presenting new developments in understanding and mitigating punching shear failure.
Overall, the publication provides comprehensive and objective information on punching shear in reinforced concrete slabs. It is intended for the engineering design community to improve the long-term strength and ductility of slab-column structural systems. Topics covered in the publication include design provisions from different codes, moment transfer strength and stiffness considerations, effects of size and geometry on punching shear resistance, shear reinforcement, and the behavior of slab-column connections under seismic and blast actions.
