The hybrid shear lag (HSL) model for hybrid fiber reinforced plastic composite I-section beam under bending loads was put forward by the principal of minimum potential energy method considering the shear deformation effect. The correctness of the HSL model was proved with finite element analysis (ANSYS). Furthermore, based on the HSL model, three conclusions were reached: first, the HSL model must consider the shear deformation effect; second, anisotropy is the main reason why the shear deformation will influence the shear lag of the composite beams; finally, four influential factors are the primary factors that affect the shear lag coefficients.
