Stress Analyzing Of Torsionand Distortion Of Box Gird

The paper gives a summary for the current technology situation of foreign and civil in the field on torsion and distortion of box gird bridges. By general bending theories, transfer matrix methods is used in the torsion and distortion of continues box gird bridges. The thesis analyses and studies torsion and distortion and cross bending of arbitrary changed section continues box gird bridges. Program about geometric nature and torsion and distortion of continues box gird bridge are compiled in Microsoft Visual C++ 6.0 language. The data results can be put out in the form of Microsoft Excel. It keep the customers out of the trouble work. They' d like to view or get the data needed in the direct drawing form, which can be altered in AUTOCAD form.
