  2. Partially prestressed concrete structure has been widely used in the field of civil engineering. the deformation is very important for prestressed concrete members, for they are thinner than those of reinforced concret owe to the adoption of hign - intension material and developed technic of design and construction. at present, there are some formulae for deformation in the criterion of many countries. mostly there are 3 methods in use : double linearity method, method of valid inertia and curvature integral calculus method. this article will discuss the influence of material, spa, construction form, and adjust the formula for stiffness of gb50010 - 2002 to a new uniform formula for deformation

    在土工程領域,部分預應力混凝土結構因其好的跨越能力和經濟性而得到了廣泛的應用,並發揮了巨大的作用。由於採用了高強度料並進一步善了設計和施工技術,預應力混凝土構件一般比普通鋼筋混凝土構件更為細巧,因此,撓曲變形問題顯得尤為重要起來。目前,各國規范對于部分預應力混凝土構件的變形計算均有相應的公式,變形計算的關鍵是剛度的計算。
