Design and Analysis of Composite Wraps for Concrete Columns

Abstract

Composite jackets for concrete columns can potentially renew deteriorated structures and improve seismic resistance. Several experimental investigations have demonstrated that composite wraps increase load carrying capacity and ductility of concrete columns subjected to axial compression. This paper describes a theoretical model to predict the nonlinear stress-strain response of the wrapped columns as a function of geometry and the constitutive behavior of the concrete and column wrap. Model predictions are compared to experimental results. The analytical equations can be used to develop relevant guidelines for optimum reinforcement efficiency as a function of column size and wrap architecture.
