进行了一项实验研究，以调查由具有高强度以及改进的耐火和耐腐蚀性的新型高性能钢制成的焊接 I 型材中残余应力的大小和分布。采用切片法测量了3个不同宽厚比的I型截面的残余应力，获得了2000多个原始读数。阐明了宽厚比的影响以及翼缘和腹板中残余应力的相互作用。研究发现，残余压应力与截面尺寸密切相关，而焊缝区域或法兰边缘的残余拉应力与截面尺寸的相关性较小。此外，未发现翼缘和腹板中的残余应力之间存在相互作用。根据试验结果，提出了能较好代表试验结果的残余应力分布模型。最后，将这种新型高性能钢与高强度钢制成的焊接工字钢的残余应力大小进行了比较。收到： 修订： 接受： 2017年10月1日 2017年11月21日 2017年12月13日
An experimental study was presented to investigate the magnitude and distribution of residual stresses i n welded I sections fabricated from a new type of high performance steel with high strength as well as improved fire and corrosion resistance. The residual stress of three I sections with various width-thickness ratios was measured by using sectioning method and more than 2000 original readings were obtained. The effects of width-thickness ratio and interaction of residual stress in the flange and web were clarified. It was found that compressive residual stress was strongly correlated with sectional dimensions, while tensile residual stress at the weld region or flange edge was less correlated with them. In addition, no interaction between the residual stress in the flange and web was identified. Based on the test results, a distribution model of residual stress was proposed which could well represent the experimental results. Finally, the magnitude of residual stresses in welded I sections fabricated from this new type of high performance steel was compared with that of high strength steel.
