| Abstract: | It presents the state of the reinforcing ultimate stress researches at rome and abroad. According to the shortcoming in the present code, based on the test result, a reinforcing ultimate stress formula for various cross - section in the bridge construction is established. Compared, the suggested formulas are verified with the experinented results and are simply into practice. |
