Effects of Simulated Corrosion and Delamination on Response of Two-Way Slabs
Publication: Journal of Structural Engineering
Volume 140, Issue 1
Abstract
This paper presents the results from an experimental program that studied the effects of simulated delamination and corrosion on the structural response of six two-way slab-column specimens with details typical of older construction. The results in terms of load-deflection response, punching shear resistance, and cracking are compared. The test results demonstrate that a reduction in reinforcing bar cross-sectional area (simulated corrosion) leads to a significant drop in punching shear resistance and results in increased crack widths. In addition, the study demonstrates that a critical degree of delamination can lead to a reduction in punching shear capacity, greater crack widths, and loss of stiffness.
