Abstract:

According to the approximate differential equation of strut, and by using Laplace integral transform, this paper obtained a new solution which is called bending moment method of Laplace integral transform, by which buckling problems of Frame can be solved. The concept of this method is clear. The method is convenient and applicable, and may be for reference in practical engineering.

Key words: Strut, Frame, Deflect curve, Laplace integral transform
