摘要

从Timoshenko梁理论出发,推导了纵向受力的弹性梁的刚度矩阵,结合工程实际例子,对纵向受力的时变弹性梁的横向弯矩进行了计算,研究分析了纵向受力对时变弹性梁横向弯矩的影响,为类似工程问题提供了一种切实可行的解决方法,对工程设计具有较重要的参考价值。
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.
