Title: Punching Shear Resistance Of Steel Fibre Reinforced Concrete Slabs
Appears on pages(s):
Abstract:The present research investigates the effects of high tensile strength steel fibres on the cracking and strength characteristics of fibre reinforced concrete flat plate slab-column connections subjected to concentric column loading and failing by punching shear. Twenty-four steel fibre reinforced concrete square slabs of dimensions 430x430x50mm are load-tested. The effects of two variable parameters on the slab experimental results are investigated. Test parameters are fibre volume fraction, which varies from 0.0% to 0.5%, 1.0% and 1.5%, and the ratio of short to long sides of the column cross-section, which has two values of 1⁄2 and 1. Based on the analyses of test results, a set of semi-empirical formulae is proposed in this paper for predicting the location of critical punching shear perimeter as well as estimating the punching shear strength of steel fibre reinforced concrete slab-column connections.
