The comparison between the test data and Billington experiential formula and ASME code shows that the formula was more accurate to the limit value in the in plane bending moment, and was very suitable for engineering application.

• 通过试验数据验证和与基于ASME规范及Billington的经验公式比较表明 ,该公式对面内弯矩极限值有较高的估算精度 ,具有较大的工程应用价值。
