Abstract: The effects of the steel reinforced concrete (SRC) short columns were investigated by experimental method.Four pillars were designed for high temperature test.The results of high temperature test show that the higher the concrete strength, the faster the temperature rise rate of the column section.The internal temperature of the circular column is higher than that of the square column, and the concrete protective layer of the circular column is more prone to burst than the square column, and the protective layer is almost completely peeled off in the high temperature test.
