Application of Engineered Cementitious Composites to Precast Beam-Column Sub-Assemblage under Column Removal Scenarios

This paper presents an experimental study on the behaviour of precast beam-column sub-assemblages under middle column removal scenarios. By using Engineered Cementitious Composites (ECC) in the beam-column joint and the cast-in-situ structural topping, the resistance and deformation capacity of the...
