- Abstract
In this study, the failure mode and shear strength of nonprestressed hollow-core slabs in one-way shear are investigated. First, nine hollow-core slabs with different void properties, such as the shape, location, and area of voids, are tested. The tests show that the nonprestressed hollow-core slabs are failed mainly by inclined tensile cracking in the compression zone, and the shear strengths of the hollow-core slabs are 20% to 30% less than that of the solid slab. Then, to estimate the slab shear strength depending on void properties, design equations based on a compression zone failure mechanism under inclined tensile cracking are formulated. For verification, the proposed method is applied to 50 specimens with a wide range of design parameters. The results show that the predictions of the proposed methods agree with the test strengths.
