Abstract:The Beijing Nanyin mansion is a highrise building with multiple functions.The prestressed RC pipe pile is used in foundation design according to the ground condition,and the calculation settlement satisfies the requirement.The frametube system is adopted in the upper structure.Some measures are applied to deal with the difficult problems such as irregular arrangement of frame and large space between columns.The analysis results of the structure show that the deformation and bearing capacity satisfy the demand3floor steel frame is set at the top of the structure.The main techniques and construction measures of the structure and the design of steel frame are presented.
