| 摘 要： | 针对实际工程中非完全卸荷加固的特点，使用计算机模拟试验方法，对对称加大截面加固混凝土偏心受压中长柱的偏心距增大系数的计算问题问题进行了研究，与试验室试验结果比较表明，该方法是符合实际的，通过对２２４根柱的电算结果的分析，提出了新的关于对称加大截面加固混凝土偏心受压中长柱的偏心距增大系数的计算公式，弥补了文献［１］的部分不足。

| Abstract: | In this paper, taking into consideration the fact that all loads will not be moved in building construction when a structure is strengthened, by the method of computer-test, we studied how to calculate eccentricity amplifier of slender concrete column strengthened symmetrically with concrete to enlarge section subjected to axial load and bending moment. By comparing with results of tests in laboratory, the results of computer-tests are proved to be reliable. After analyzing the computer-test results of 224 columns with different parameters, a new formula is suggested to calculate the eccentricity amplifier of slender concrete coltumn strengthened symmetrically with concrete subjected to axial load and bending moment. Partially it makes up the dEficiency in reference 1]. |
