Abstract: Combining the strengthening methods of reinforced concrete structure and the relevant area parameters of the section characteristics about the reinforced concrete members after fire, giving the unified formula of eccentric compression members about reinforcement amount, and applies it into a variety of reinforcement method. Though the case, reflecting the formula in the calculation of the structure reinforcement after fire with a simple, accurate and fast features. 

Keywords: fire; eccentric compression members; the unified formula; reinforcement amount
