| Abstract: | A continuous parallel model is taken as the computational model for the second-order analysis of tall frame -shear wall structures with varied sections, considering the floor slab deformation by use of the piecewise technique. The second-order analysis differential equations for the model are then derived. Morever, the second-order displacements and internal forces are determined numerically by means of the ODE (Ordinary Differential Equation) solver, which is a program developed for solving various ODEs. Lastly, the factors that influence the second-order effects are discussed. |
