According to theoretic analysis, computing the bending deflection of every roller is enabled to ignore the effect of the web and only allow to the rectangular section made up of flange plates.

理论分析认为求解各可调辊的压下挠度时，可以不考虑腹板的影响而按翼缘组成的“矩形”断面来进行。

Deflection, the total tendency is under the similar load, along with the web plate high increase, the built-up beam rigidity is increasing, amount of deflection unceasing reducing.

对于挠度来说，总的趋势是在同样的荷载下，随着腹板高度的增加，组合梁的刚度在增加，挠度不断的降低。

The test result shows that deflection of CFST truss girder is mainly attributed to deformation of shear-bending parts and much smaller than that of solid web girder.

试验结果表明：钢管混凝土桁梁变形比实腹梁小很多且主要集中于边段；
