A Study on the Fire Resisting Properties of Reinforced Concrete Structures

Abstract

Concrete is incombustible and has good fire resisting properties, i. e. when exposed to fire it continues to perform satisfactorily for a reasonable period of time. Nevertheless, with time and high temperature gradient, brought about the fire, causes cracking and spatting. Further deterioration and loss of strength are caused by gradual dehydration of concrete paste. This paper is aimed to make a proposal for the design and construction of reinforced concrete structures with more sufficent resistance to fire by the theoritical analysis, which is base4 on investigation of general damages by the fire and change of properties on concrete influenced by high temperature.
