| Abstract: | Considering the shear capacity of elastic foundation and the shear deformation effect of beam,the equilibrium equation for Timoshenko beam resting on two-parameter foundation was derived.The initial parameter solution and transfer matrix method were presented.Using the initial parameter solutions,the finite element formulation and equivalent nodal forces of distributing load were deduced.When the shear rigidity of foundation was zero,the two-parameter foundation could be degenerated into Winkler foundation.... |
