Abstract: Box beam shear lag effect of single-cable-plane cable-stayed bridge under bending moment and axial force is analyzed in this paper. Taking one Yellow River Bridge in Jinan as an example, the formula of shear lag under dead load has been set up using the Energy Variation Method. It is convenient and practical. The theoretical calculation results are in good agreement with those obtained in the solid finite element model. The results show that the shear lag effect of single-cable- plane cable-stayed bridge with wide box girder is bigger. It should be highly valued in the design.
