Abstract

Tests were performed to measure shear strength by punching five (5) isolated footings of reduced size and supported on granular matter. Footings were squared, 450 mm by side and 80 mm thick, reinforced with bars, 6.3 mm in diameter and 3.5 slenderness (a/d). Estimation of failure loads predicted by three codes (ACI-318-14, Eurocode-2, and BS-8110) were made to analyze parameters' influence that, according to each norm, affect shear strength by punching. Results show that the methodology of one of the codes analyzed is more conservative than the others.
