摘要
使用计算机模拟试验方法，考虑了实际工程中非完全卸荷加固的特点，通过对５４０根具有不同参数柱的研究分析，提出了加大截面加固混凝土偏心受压中长柱的二阶挠度计算公式。
After 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, the computer-test results of 540 columns with different parameters are analyzed, a formula is suggested to calculate the secondary deflection of slender concrete column strengthened with concrete subjected to axial load and bending moment.
