( Beijing Construction Engineering Research Institute Co., Ltd., Beijing 100039,China)Abstract: The project of transformation of National Stadium is to demolish part of steel reinforced concrete beams and columns, and strengthen the regions where the structures were demolished. In order to ensure the structural safety of removal process, the deformation and stress of structure were monitored, and the results of monitoring were analyzed in detail. The results show that the deformation and stress of the remaining structure are within reasonable ranges, the demolishing of National Stadium is successful.
