| Abstract: | According to the engineering case,the article puts forward the simplifying calculation method of pre-stressed concrete continuous box girder with the obvious torsion effect,which is to simplify the integral space model of the pedestrian overpass with the torsion effect to the plane framed model for calculation.After the comparison and analysis of the integral calculation and simplifying calculation results,it is to make clear that this simplifying calculation method is effective and feasible able to meet the security and precision requirement of engineering design. |
