摘　　要：阐述了预设偏心能改善独柱支撑曲梁受力特性的原理,通过实例分析设置不同偏心值对相同半径曲梁内力的影响、以及不同偏心值对不同半径曲梁的内力影响,并得出了具有一般规律的特性。The principle that presupposed off-center can improve the mechanical behavior of the single-column supported curved beam was explained in this paper. The influence of different off-center values on the internal forces variations of curved beam with same radius was analyzed based on some examples. The influence of different off-center values on the internal forces variations of curved beam with different radii caused was also given. Some common characteristics were obtained.
