摘要
本文论述了网架支座预加压力使网架产生预应力的简化计算方法，先假定网架的抗剪刚度ｃ＝∞，求出网架的挠度ｗ０，进而求出ｃ≠∞时网架的挠度ｗ和转角．本方法计算简单，可供设计工程师参考。
In this paper,a simplified calculation method of space trtisses with precompressed supports is discussed.Assuming the shear rigidity of space trusses to be infinity i.e.c=∞,the solution of their deflection w0 is obtained firstly,then the deflection w and rotational angles of space trusses as c ≠∞ can be solved.The given method is clear in conception and convenient in calculation.A numerical example is shown for reference in designing.
