摘　　要：目前,对缀板柱的理论计算还停留在弹性阶段,实用计算方法近似程度较大。本文给出缀板柱的数值积分解法,可以计算出缀板柱极限承载的全过程,精度足以代替试验。At present, theoritical studies of battened columns still remain in the elas-tic stage. A numerical integration method for the analysis of stable ultimatestrength of battened columns is presented in this paper, which can predictthe whole process of loading from elastic state to failure and unloading. Pre-cision of the proposed method is so high that it can be used to replace experi-ments.
