Actually the proposed formulas for calculating the overall stability capacity mostly focus on the double-symmetric I-section beams, and in which the influence of the loading position and the monosymmetry section constant have not been fully accounted for. 现今学者们提出用于计算悬伸梁和连续梁的整体稳定承载力计算方法多针对双轴对称截面,而且荷载作用点高度和截面不对称性对整体稳定性能的影响考虑的不够全面。
