| 摘 要： | 通过在双模量理论中引入偏离量e,消除部分压杆截面性质变化所造成的影响,得出来的P_(r1)与P_r和P_t的关系既有理论意义又实用。修改后的双模量理论使得双模量理论与切线模量理论之间的矛盾得到解决。

| Abstract: | This article through introducing means of eccentricity e in the formula with bimodulus,eliminates influence which the partial column on sections nature change creates,obtains relations P_(r1) and P_rand P_t the both has the theory significance and to be practical.After the revision the formula with bimodulus enables the formula with bimodulus to be solved with the formula with tangent modulus between contradiction. |

| Keywords: | intermediate column elastic-plastic buckling the formula with bimodulus |
