Overview on Strengthening Design of Workers" Stadium in Beijing/Li Jianguo,Wang Yi,Wang Lixin(Beijing Institute of Architectural Design, Beijing 100045,China)

Abstract: Beijing Workers Stadium, completed in 1959, needs a seismic strengthening in order to fulfill the requirements of the 2008 Olympics Games. The structural characters and seismic defection of the stadium are introduced. It presents several strengthening schemes, such as adding damper, using carbon fiber sheets, external prestressing, in consideration of the strengthening effects, capital saving and construction feasibility, etc, paying more attention to improve the structural system and the whole seismic ability, having made a good result, providing important references for similar strengthening projects.
