【Abstract】 In this paper, a piecewise continuous model is taken as the computational model for the overall stability analysis of tall stepped building with frame-shear wall-thin walled core skewly combined structure.The stability differential equations for the model are derived. Moreover, the critical load and the corresponding buckling mode are determined numerically by means of the ODE (Ordinary Differential Equation) Solver, which is a program developed for solving various ODEs, including eigenvalue problems.更多还原
