Abstract

In this paper, based on the principle of complementary energy, the formulas for calculating the bending stresses, deflection, and shear lag effect of composite laminated boxbeam were derived by means of the variational calculus. The comparison between numerical results of this paper and those of the References12 based on the principle of minimum potential energy is made which shows that the results are in good agreement.
