摘要
介绍了钢构件中残余应力的形成、分布,就不同分布的残余应力对轴心受压杆件引起的应力过程变化进行研究.研究表明:残余应力对于不同长细比构件的整体稳定承载力影响不同.
The paper introduces the formation ,distribution of residual stresses in steel structures .It analyses and compares the effect of differently distributed residual stresses on the variation of stresses of axis compressed steel members . The study shows that residual stresses have different effects on the members 'carrying capacity because of different slenderness ratios
