  • In this paper, by using a simplified mechanical model on subarea in tension and compression, the analytical solution of bimodular simply supported beams under uniformly distributed loads was derived without the assumption of plane section.Based on the numerical iteration technique from bimodular finite element method, the shear modulus used for accelerating convergence was introduced and the numerical iterative program for the same problem was rebuilt.Using this program, bimodular beams in the cases of different ratios of elastic moduli in tension and compression, including from shallow beams to deep ones, are computed.The numerical result shows that different ratios of elastic moduli has great influences on the bending stresses and the vertical deflection of bimodular beams.By contrasting the numerical results with the analytical solutions, the applicable range of the analytical solutions presented in this paper was determined.
