| Abstract: | Taking the effect of non-radial bearings in the beam-ends into consideration, the rigid-crossbeam method was used to calculate the load lateral distribution of curved beam bridge with non-radial bearings as to get more accurate results. Then according to some related parameters, the corresponding form was made to suit the engineering designer's convenience. And also the trail of rotating center was abtained, which is one of the important characters of multi-beam bridge. |
