摘要
由于钢材规格较薄,腹板塌陷是冷弯型钢的常见故障。高腹板塌陷率就是这种梁失效的结果。过去的研究已经讨论了基于不同梁厚度的腹板残余范围。然而,对腹板残余的优化却没有进行研究。有鉴于此,本研究工作利用秃鹫优化功能研究了如何降低腹板瘫痪率。因此,本研究提出了一种新颖的智能秃鹫决策模型(IVDM)来确定适当的 Z 截面梁厚度,从而降低了腹板瘸腿率。通过研究冷弯钢 Z 型截面梁在点荷载、均匀分布荷载和偏心荷载三种不同荷载情况下的强度,确定了该梁的强度。此外,Z 型截面梁是在 ABAQUS 平台上设计的,而设计模型是在 MATLAB 环境中运行的。通过执行不同的执行轨迹,可以预测适当的梁厚度范围。因此,Z 截面梁的最佳梁厚度值是通过 ABAQUS 软件设计出来的。最终,所有其他结果参数都表明,与其他已在使用的模型相比,建议的模型具有更高的强度和更少的网络瘫痪。与现有方法相比,所建议的 IVDM 将腹板跛行率提高了 4%。经过验证,引入的模型非常适合网络瘫痪应用。
An Optimally Designed Cold-Formed Steel Beam Thickness Selection for Reducing Web-Crippling Smartly
Web-crippling was a usual failure in cold-formed steel due to the thin gauge steel. The high rate of web-crippling is the result of this beam failure. Past studies have discussed the web crippling range based on different beam thicknesses. However, the optimization of web crippling is not studied. Considering this, the reduction of web crippling rate is studied in this research work with the use of vulture optimal features. Henceforth, the current study proposed a novel intelligent vulture decision model (IVDM) to determine the proper Z-section beam thickness, which has reduced the web-crippling rate. The Strength of the cold-formed steel Z-section beam was ascertained by examining the beam’s Strength under three distinct loading scenarios: point load, uniformly distributed load, and eccentric load. Additionally, the Z-section beam is designed on the ABAQUS platform, while the designed model is run in the MATLAB environment. Performing the various execution trails allowed for predicting the appropriate beam thickness range. As a result, the optimal beam thickness value for the Z-section beam is designed using the ABAQUS software. Ultimately, all other outcome parameters have shown that the suggested model has higher Strength and less Web-crippling compared to other models already in use. Here, the proposed IVDM has improved the web crippling rate by 4% than the compared existing approaches. It has been verified that the introduced model is highly suitable for web-crippling applications.
