现今规范中的双向压弯构件的稳定验算公式中的弯矩放大系数都是套用平面内的弯矩放大系数，它是建立在有限的试验基础上的，是一个半经验半理论的设计公式。
The current biaxial bending design formula always use the moment magnifier factor of in plane bending, which based on finite tests data, it's a semi- theoretical -semi-experience formula.
在结构设计中，选择一个合理的中梁、边梁刚度放大系数和选择一个合理的梁端弯矩调幅系数一直没有得到一个统一的值。
In construction design, there is still no a reasonable uniform cost about the rigidity amplification coefficient of center beam and boundary beam.
