Title: Shear Resistance of One-Way Slabs Under Concentrated Loads
Author(s): P. E. Regan and H. Rezai-Jorabi
Publication: Structural Journal
Appears on pages(s): 150-157
Keywords: concrete slabs; loads (forces); one-way slabs; punching shear; reinforced concrete; shear properties; Structural Research
Abstract:Twenty-nine tests of one-way spanning slabs subjected to concentrated loads and failing in shear are reported. It is shown that analyses using current code provisions and making separate calculations of full-width one-way shear strengths and punching resistances are inappropriate. It is proposed that component shears due to symmetric load spreading and longitudinal spanning should be summed and equated to a limit value. This approach is shown to correlate well with the results of the reported tests and others in the literature.
