摘要
残余应力是降低厚板焊接柱极限承载力的重要因素之一。本文用切割法对焊接箱形截面柱的残余应力分布进行了实测,并对其分布特征进行了分析。
Residual stress is an important factor reduced the ultimate load of the heavy weldedcolumn. Using the sectioning method, the residual stress distribution in the heavy weldedbox-section is measured. Further, the typical features of the residual stress distributionare analysed.
