| 摘要: |
| 针对现行混凝土结构设计规范GBJ10-89中，偏心距增大系数η计算公式在应用中存在的缺陷，在考虑二阶弯矩影响的有限元迭代法计算成果的基础上，通过大量计算，并运用回归分析，建立了钢筋混凝土受压构件η的计算表达式。该公式简单、实用、运用范围广，可直接用于结构设计。 |

| Abstract: |
| In view of the defects of increase coefficient of bias distance η formula (GBJ10-89)in practice,considering the result of the limitstate alternative method resulted from the effect of the second coracte moments,by regression analysis and after much calculalion,the regression count expression formula of increase coefficient of bias distance is established.The formula is simple,practical,widely used,and can be used directly in construction design. |
| Key words: bearing pressure element,increase coefficient of bias distance,regressionanalysis,moment, |
