| Abstract: | A reinforced concrete bridge with simply supported beams in Yancheng was strengthened by external prestressing because of its excessive deflection,but effect was little.This paper checks the original design and the strengthening scheme of the bridge,points out the inappropriate parts in the strengthening scheme and main reasons of the strenthening failure,and suggests another strengthening scheme. |
