| Abstract: | The strengthening methods of superstructure of bridge are elaborated. according to bridge deck reinforcement method, enlarging beam area method and adding steel bar method the stress state of T-type beam after reinforcement is analyzed. Examples are also listed to demonstrate enlarging-area approach and adding main steel bars method. In the end comparison is made between of them. |
