Abstract
This chapter presents the development and validation of a three-dimensional (3D) finite element (FE) model to predict the axial compressive behavior of engineered cementitious composite (ECC) confined concrete encased steel (ECC-CES) short composite columns. The FE model incorporates both material and geometric nonlinearities along with the initial geometric imperfections. The material behavior of different components including ECC, concrete and steel under tension and compression are described using appropriate constitutive laws. The effects of ECC and steel confinement on the concrete core as well as strain softening behavior of steel under compression are considered. The results of the FE analysis are compared with experimental results and good accuracy is demonstrated. In addition, a detailed parametric study to investigate the effects of extended range of material and geometric parameters on the compressive performance of ECC-CES column is conducted using the validated FE model.
