Abstract
This chapter presents the results of a comprehensive experimental study on the axial compressive behavior of newly introduced engineered cementitious composite (ECC) confined concrete encased steel (ECC-CES) short composite columns. The effects of various key design parameters including materials' (ECC, concrete and steel) strength, ECC cover thickness, steel plate slenderness, and column cross-section shape and configuration on columns' performance are investigated. The structural behavior of ECC-CES columns is evaluated and discussed in terms of failure modes, load-deformation response, ductility, and toughness. Moreover, a detailed strain analysis is performed to understand the damage progression of different components in ECC-CES columns. In addition, a simple strength prediction formula to calculate the ultimate compressive capacity of ECC-CES columns is also proposed based on the effective stress method.
