Research on key problems of structural design of a bottle shape super high-rise building with core setback
A super high-rise building in Wuhan is located in the riverside area of Hanyang District.The overall shape is a bottle shape that gradually divides the lower and upper parts.The main structure is 249m in height,with a 51m-high tower crown on the roof,and the total height of the building is 300m.The architect requires that the frame columns should be arranged next to the curtain wall,so that most of the columns are inclined columns,which will generate horizontal force on the floor system under the action of vertical load.In the design,tensile reinforcement and steel are set in the floor beam to bear the horizontal tension.The core wall setback has been converted on the 17th and 43rd floors,and through reasonable analysis and measures,the rationality of the way of wall force transmission was ensured.The wind tunnel test and related demonstration of the main structure was carried out,which reduces the design wind load and saves the structure cost.The construction simulation,shrinkage and creep analysis,wall finite element analysis and tower crown analysis were carried out,the results indicate that the structural design is safe and reasonable.
