Working Stress Method

Technical Civil

This is the traditional method of design, used not only for reinforced concrete but also for structural steel and timber. This method of designed was evolved around the year 1900. This method was accepted by many national codes. India’s code IS:456-1953 was based on this method. It was revised in 1957, 1964, 1978, 2000 and reaffirmed in 2005 and its tenth reprint was in 2007.  This method is based on linear elastic theory.  This method ensures adequate safety by suitably restricting the stresses in the materials induced by expected working…
