矩形等截面直梁的预弯曲变形研究

The Study On Pre-deflecting Distortion About Over-Arm Of Square Equal Cross-Section

文中应用弹塑性变形理论，对矩形等截面直梁构件预弯曲变形进行了探讨，推导出的计算公式实用、方便，能有效地指导生产，为优质、快速生产预弯曲等直构件提供了依据．

The article analyses pre - deflecting distortion about over - arm of square equal cross- section by means of applying the theory of elastic and ductile distortion. The calculated formulas that were derived from it are applied facilitated and efficiently direct production. Meanwhile, we can product rapidly the best quality provision of pre - deflecting distortion by using the formulas
