| Abstract: | Combined with the engineering practical example, the article puts forward the simplifying calculation method of the irregular pre-stressed concrete continuous rigid frame bridge when the lengths of various webs are more different, that is, the obvious space effects of the irregular rigid frame bridge are simplifies to the plane member system structure for calculation, and demonstrated and analyzed through the space finite element. The result makes clearly that this simplifying calculation method is effective and feasible, which is able to meet the safety and accuracy requirement of the engineering design. |
