Narendra Kumar Kolli Ramujee Journal on Structural Engineering 2320 - 2343 5 1 1 10 Glass Fibre, Steel Fibre, High Strength Self Compacting Concrete, Stress-Strain, Analytical Models, Ductility, Toughness In the present study, High Strength Hybrid Fibre Self-Compacting Concrete (HSHFSCC) is developed from High Strength Self-Compacting Concrete (HSSCC) using hybrid fibres by varying the proportion of steel and glass fibres with total fibre content to 1.5% of power content based on its rheological and hardened properties of concrete. This research mainly aims at utilizing the best attributes of earlier models and proposes a new stress-strain model that can well represent the stress-strain behaviour of HSSCC and HSHFSCC. Analytical stress-strain models are proposed to predict the stress-strain behaviour of HSSCC and HFHSSCC based on the results of experimental investigations. The proposed empirical equations can be used as stress block in analysing the flexural behaviour of HSSCC and HFHSSCC. March - May 2016 Copyright © 2016 i-manager publications.
