【摘要】 本文在分析国内外有关预应力混凝土结构等效荷载计算方法的基础上,建立了新的计算等效荷载方法,并得出了预应力混凝土结构的性质,提出了“广义预应力”的思想,研究了体内预应力混凝土结构的变形,分析了体外预应力混凝土结构变形中几何非线性问题的影响。 本文研究表明:预应力效应是多方面的,任何复杂的结构都可以使用预应力技术;体内预应力混凝土结构变形不存在几何非线性问题;而体外预应力混凝土结构变形中几何非线性的影响不容忽视。

【Abstract】 In this paper, on the basis of analyzing methods to calculate equivalent loads in the world, a computing method of equivalent loads is presented, and prestressed concrete property and generalization prestressing force are deducted. This paper studies internal prestressed concrete deflection and analyze the effect of geometrical nolinearity on external prestressed concrete deflection.This paper shows that prestressing force effects are comprehensive, which extents the application of prestressing force technology. The effect of geometrical nolinearity is not had on internal prestressed concrete, but must been regarded on external prestressed concrete.
