(CISDI Engineering Co., Ltd., Chongqing 400013, China)Abstract: Earthquake disaster for steel-tube intercolumnar brace of steel structure factory buildings in the Wenchuan Earthquake is analyzed. Direct-welded joints of steel-tube are not provided with plastic deformation capability, and lead to damage by stress concentration. In the paper details of steel-tube intercolumnar brace are improved.
Keywords: steel-tube structure, earthquake disaster, intercolumnar brace, details
