| Abstract: | With the development of economy super tall building is more and more po pularization. Steel structure and steel tube concrete structure with giantism raking strut,giantism post,giantismframe structure are also used by super tall bui lding. The specification and working accuracy of this kinds of steel structure c omponent are very strict. The new process technology and technical requirement of large diameter thick wall steel tube for super tall building are discussed.The measures of prevention of welding cra... |
