【Abstract】 Based on shear beam theory,the closed-form analytical expressions are derived for participation factors and steady-state dynamic response functions by using the modal-superposition method and orthogonal property of modal displacements.Finally,using Runge-Kutta method,the maximum responses(including the displacement,the acceleration,and the shear stress) are obtained.更多还原
