Influences of Welding Residual Stresses on Performance of Steel Structures and Methods for their Elimination

Abstract:

Weld connection is the major connection method for steel structures, which has the advantages of simple construction, economical materials, non-reduced section, convenient fabrication and processing and good tightness, but the residual stresses caused by welding have relatively great impact on the performance of steel structures. This paper mainly analyzes the influences of welding residual stresses on static strength, stiffness, stability, fatigue strength and low temperature performance of steel structural members, and describes the main methods for eliminating residual stresses, in order to reduce and eliminate the residual stresses, and improve the security of structural members.
