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。
The calculated results show that the difference of the calculated results by three calculation methods is rather big for short columns , but the difference of the calculated results is small at the large slenderness ratio . with eccentricity rations decrease , the difference of the calculated results increase . now the difference of the theory and results of calculation is large in the three specifications 计算结果表明：对于短柱，按三本规程计算的承载力结果较为离散，最大相差37 . 7 ；对于中等及较大长细比柱，三本规程下的计算结果较为接近，但随偏心距的减小，三者的计算结果相差增大；我国目前的三本规程所给出的计算理论和计算结果都有很大差别。
