Abstract
Taking nonlinear characteristics and shear deformation of steel and concrete into consideration, virtual work principle based on FEM is used to derive control differential equations and boundary conditions for static force analysis of RC beam. The control differential equations are transferred to six first order ordinary differential equations for nonlinear differential boundary value problems. Nonlinear shooting method is adopted to study on statics behavior for acquiring displacement and bending moment response. Compared with Timoshenko and Euler-Bernoulli analysis,
deployment analysis and parameters are tested to be correct. Additionally, shear effect and moment analysis tests results in moment modulation coefficients.
