Abstract

Ductility ratio and toughness index were studied for two -way reinforced concrete slabs subjected to high temperature and cooling. . Empirical equations were developed to predict the ductility ratio and toughness index ( in terms of temperature and reinforced ratio) of such slabs under uniformly distributed load . These proposed equation gave good agreement when compared with the experimental results, with a correlation factor for ductility ratio and toughness index of 0.94 and 0.95 ,respectively.

Keywords: - slabs, ductility ratio, toughness index, high temperature, two-way slob, ductility, reinforced concrete.
