Abstract EN
HSC normally suffers from low stiffness and poor strain capacity after exposure to high temperature.
High strength confined fibrous concrete (HSCFC) is being used in industrial structures and other high rise buildings that may be subjected to high temperature during operation or in case of an accidental fire.
The proper understanding of the effect of elevated temperature on the stress-strain relationship of HSCFC is necessary for the assessment of structural safety.
Further stress-strain model of HSCFC after exposure to high temperature is scarce in literature.
Experimental results are used to generate the complete stress-strain curves of HSCFC after exposure to high temperature in compression.
The variation in concrete mixes was achieved by varying the types of fibre, volume fraction of fibres, and temperature of exposure from ambient to 800°C.
The degree of confinement was kept constant in all the specimens.
A comparative assessment of different models on the high strength confined concrete was also conducted at different temperature for the accuracy of proposed model.
The proposed empirical stress-strain equations are suitable for both high strength confined concrete and HSCFC after exposure to high temperature in compression.
The predictions were found to be in good agreement and well fit with experimental results.
