Abstract

This chapter presents the numerical investigations of the flexural behavior of engineered cementitious composite and lightweight concrete (ECC-LWC) encased steel composite beams. A detailed three-dimensional nonlinear finite element (FE) model was first developed using ABAQUS and then validated against the test results. Finally, a parametric study was carried out using the validated FE model to further investigate the influence of different encasement parameters on the flexural behavior of the proposed composite beams. The numerical study results indicated that steel grade, flange thickness, and web thickness were the key parameters for improving the flexural strength of the beams studied. The numerical results further demonstrated that a configuration of the beams with only the top 25% of the steel section encased in ECC and a 25-mm ECC cover to the steel flange is the most efficient cross-sectional design investigated in this study.
