Shenzhen Guangdong 518100 China; 2.China Construction Third Engineering Bureau Co.Ltd.Wuhan Hubei 430070 China) Abstract:Guangzhou Pear River New Town West-tower is a tube-in-tube structure whose steel structures need lots of steel.During the reeling pressing and welding of steel pipes residual stress is generated so eliminating residual stress is important for structure quality.The eliminating residual stress method of vibratory stress relief and straight pipe vibratory stress relief are introduced technology requirement of treated ponents is also described.The technical parameters of steel pipes and nodes vibratory stress relief the implementation process and effect of loeal control heat treatment method are put forward.The eliminationg method can imporve structures total bearing capacity and also enhance safety of the structure. Key words:residual stress;eliminating method;vibratory stress relief;local...
