矩形管翼缘开孔波纹腹板钢梁抗剪性能试验研究

open access: yesJianzhu Gangjiegou Jinzhan
为研究矩形管翼缘开孔波纹腹板钢梁的抗剪性能,设计完成了四个试件的受剪试验。通过分析试件的破坏模态、荷载-位移曲线和关键区域的应变发展规律,研究了试件的抗剪性能、极限承载力及波纹腹板在开孔后分担的剪力比例。利用ABAQUS进行了数值模拟,将模拟结果与试验结果进行对比,验证了有限元模型的正确性。研究了腹板几何初始缺陷和开孔偏移对抗剪承载力的影响。结果表明矩形管翼缘开孔波纹腹板梁具有较好的延性性能;其抗剪承载力会随着开孔孔径的增大而降低,腹板波纹越密集,抗剪承载力越高;开孔横向偏移对抗剪承载力影响不明显 ...
