Applying the equivalent section method to solve beam subjected to lateral force and bending-compression column with different moduli

Based on elastic theory of different tension-compression moduli, bending beam subjected to lateral force and bending-compression column with different moduli were solved by the equivalent section method. Formulas for the neutral axis, normal stress, shear stress and displacement were developed also. This equivalent section method can turn conveniently different moduli problems into the similar moduli ones, i.e., classical elasticity problems so the existent results aimed beams and columns with similar moduli both can be used indiscriminately without complicated derived process. Compared with the present derived method based on different moduli theory the applicability and efficiency of equivalent section method is demonstrated.
