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；
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.
在人们认识了实腹式梁的受力特征后，逐步将其部分腹部材料掏空，形成了平面桁架梁。
Having known the characters of the solid abdomen beam, people begin to remove some material in abdomen of the beam, thus the plane truss beam is formed.
