Abstract:Xizhimen Exchange Hub Project is a complex largescale public engineering with multifunction.The highrise multitower structure is divided into several parts by earthquake clefts.The frame shearwall system is adopted in the main structure,and the steel large span vierendeel truss is applied in the corridor structure.The steel arch is used in the roof, and the rigidity poles and space cable pole network are composed to the vertical bracings.The postpressure grouting bored pile is used in the foundation design.
Keywords:multitower; large basement; frameshear wall system; vierendeel truss; postpour grouting bored pile
