预应力构件锚固区的局部应力分析和构造设计

The local stress analysis and component design of pre-stress component anchor area

从预应力构件的局部应力分析入手,提出了预应力构件锚固区角焊缝的尺寸限制及计算公式,探讨了腹板加劲肋的配置,进行了无局部压应力作用的梁腹板的稳定计算,可供预应力构件进行细节设计时参考。

Based on local stress analysis of pre-stress component, it puts forward the size limitation and calculation formulary of pre-streas component anchor area fillet weld, discusses the collocation of web reinforced, and gets the stability calculation to the beam web when has no local stress, and this can be the reference to gets the detail design to the pre-streas component.
