Abstract

The concept of failure localization in concrete is discussed and extended to include compressive failure. For tall compression members, severe snapback in the load-deformation curve is found while relatively ductile behavior is observed in shorter specimens. To study this localization phenomenon, a feedback control method which computationally subtracts part of the elastic response of the specimen in order to obtain a stable feedback signal even when severe snapback occurs is employed. This test method is described in detail, and results from experiments on cylinders of normal and high strength concrete with height to diameter ratios ranging from 2:1 to 5.5:1 are presented. Implications of these results on design codes are discussed along with suggestions for future studies in this area.
