残余应力在钢材或钢构件中的存在虽然很早就已发现,但有目的地大规模地对其测定,比较深入地研究它对压杆承载力的影响,只是近二、三十年的事。至于将残余应力的研究成果应用到设计、施工实践中去,主要是七十年代实现的。本文除对残余应力的产生和量测做一般性介绍外,将着重叙述热 Although the existence of residual stress in steel or steel components has been discovered for a long time, it has been purposely determined on a large scale, and its influence on the bearing capacity of compression rods has been studied in-depth. It is only two or three decades. . As for the application of residual stress research results to design and construction practices, it was mainly realized in the 1970s. In addition to the general introduction to the generation and measurement of residual stress, this article will focus on the
