摘要
分析了影响结构件抗弯性能的因素和各因素对抗弯性能的影响规律,并提出了提高结构件抗弯性能的思路方法。结果表明,影响结构件抗弯性能的主要因素有外力F、材料弹性模量以及构件形状参数;在外力、构件形状以及材料一定的情况下,增加构件的截面宽度B、截面高度H、厚度d或者减小长度L均有利于提高结构件的抗弯性能;材料弹性模量越大,结构件抗弯性能越好,相对于Q235普通钢,Q500和Q700高强钢结构件的抗弯性能分别提高4.21%和9.98%;采用高强钢和优化结构件形状参数相结合的措施,对提高结构件的抗弯性能具有很好的效果。
Factors influencing the bending properties as well as the influencing patterns of each factor on the ben-ding properties of structural steel were analyzed while measures to improve the bending properties were proposed. The results showed that external force F,elastic modulus and shape parameters were the main influencing factors. With constant external force, increasing the cross-sectional width B, height H and thickness d or reducing the length L can improve bending properties. The higher of elastic modulus, the better of bending properties; the bending proper-ties of Q500 and Q70Q high strength structural steel were improved by 4, 21% and 9. 98% , respectively, compared with that of Q285. Adopting the combined measure of using high-strength steel and optimizing the shape parameters can effectively improve the bending properties of structural steel.
