Abstract

Abstract

Mega hybrid frame-corewall structure is a new type of structural system for super high-rise buildings,which consists of mega SRC frame,RC corewall,and outrigger trusses.The lateral stiffness and cooperative working performance of structure can be effectively improved by using methods as follows: increasing the stiffness of mega beams and outriggers,setting mega braces on the mega frame.The analysis results indicate that using these methods can improve the lateral stiffness and reduce the stiffness irregularity.The transmission efficiency of internal forces between the substructure and the main structure under vertical load can be improved by setting mega braces as well as increasing the stiffness of mega beams.The axial force of core wall can be reduced by increasing the stiffness of outrigger under vertical load,therefore,the earthquake-resistant capacity of core wall can be improved.The bottom shear force and moment of the mega frame under earthquake can be increased significantly by setting mega braces.
