In the construction process of super tall cantilever platform,the influence of cantilever end load on shear wall should be considered.Based on a project in Guangzhou,a prestressed steel rod is welded on a 30-38th-story core steel column,and the rod is stretched through tensile operation,thus generating a downward tension,which can offset the upward tension of the overhung platform load on the shear wall,and greatly reduce the possibility of the concrete being pulled apart,which ensures the safety of the construction process and meets the construction quality requirements.
