| 摘 要： | 通过一实际工程分析了初始内力对粘钢加固圆柱正截面承载力的影响。基于材料的应力应变关系,编制极限状态下粘钢柱正截面承载力的计算程序,分别在大小偏压的初始内力作用下研究粘钢柱承载力的变化,并说明平截面转动轴不平行于初始弯矩方向时,极限弯矩与平截面转动轴不平行的现象。根据研究的结果,针对一实际工程提出考虑初始内力双偏压圆柱的抗震加固截面验算方法,其中包括了双偏正截面承载力包络面的计算、二阶效应与抗震承载力调整的处理方法。

| Abstract: | Initial force effect for flexure capacity is studied for strengthened-steel circular columns of a practical project.Based on the constitute equations of materials,the calculation of flexure-compression capacity of ultimate status is programmed for the column with strengthened steel.The capacity of strengthened column is exploded with both great and small eccentricity compression of initial forces.The result shows that the direction of ultimate moment is unparallel to the plain section rotation axis when the... |
