Abstract : experimental researches on normal section ultimate fle xural strength of prestressed reverse - rib - slab with excessive steel bar were m ade , and according to chinese norm ( gbj10 - 89 ) and american norm ( aci ) in which s train harmony analysis method was adopted , its ultimate strength was calculated , these make us further realizse the ultimate flexural strength of prestressed r everse - rib - slab with excessive steel bar 文摘:通过叠合结构中预应力超筋倒肋薄板正截面极限承载力的试验研究，分别采用规范gbj10 - 89中的受弯构件、偏心受压构件的计算公式及美国aci规范中的应变协调分析方法计算了极限承载力，从而更清楚地认识了配有高强钢丝的超筋倒肋板的极限承载力计算问题。
For the sake of grasping completely the performance of component under eccentricity compression by prestressed strengthening method , the eccentricity loading components under the different value of prestressed forces and the change of eccentricity distance were designed in details on basis of the bearing properties of it 依据偏心轴压构件的受力特点，为了完全掌握预应力法加固偏心受压构件的性能，本文对偏心受力构件进行了详细设计，如预应力的取值变化、偏心距的变化等。
