桁架结构计算方法探讨

笔者在深入研究了桁架结构的经典计算方法之后,提出了一种新的计算方法——“轴力系数趋势平衡法”.这一方法不用力的投影平衡方程而使用了轴力系数的“趋势平衡”方程进行计算,从而在许多情况下使繁锁的桁架计算变得异常简捷。文中推导了方程,叙述了基本原理与方法,并通过例题证明了该方法的正确性与优越性。

A New Method of Truss-structures Calculation

The author has put forward a new method of truss-structures. calculation after a thorough study on traditional method. The new method, which is called "the trend equilibrium method of axial force coefficients", applies trend equilibrium equation of axial force coefficients instead of force projection equations. Thus, The complicatead truss-calculations become extremely simple. In this paper. the author has explained the fundamental principle and methods, and has deduced the equations. Examples are also given to show the new method to be correct and superior.
