【Abstract】 The geometric stiffness matrix is developed based upon Timoshenko beam theory for axial-loaded elastic beam in this paper.For an engineering practical example,it is calculated that the transversal bending moment of axial-loaded time-varied elastic beam,and the effects of axial-loaded force on transversal bending moment of time-varied elastic beam are analyzed.The proposed method in this paper is effective for solving similar engineering problem,and is valuable for engineering design.更多还原
