Anti-wind Performance And Anti-seismic Performance Analysis Of Mega Frame Structure System

Mega braced frame structure system is a new kind of special (super) high-rise structuresystem and it is put forward that combine the advantages of mega frame structure system andmega truss structure system. For the (super) high-rise structure system, the horizontal lateral loadis the deciding factor, hunce, need a deep research and analysis to anti-wind performance andanti-seismic performance of mega braced frame structure system.This paper mainly summarize basic theory of anti-wind and anti-seismic. Using finiteelement software SAP2000for the performance comparison analysis of mega braced framestructure system and mega frame structure system under the action of wind load and seismic load;And then, for the performance comparison analysis of mega brace of different mega bracedframe structure system; Finally, established the calculation model and motion equation of themega braced frame with energy dissipators structure system and for damping effect analysis.According analysis to conclude, in the similar of steel quantity, the rigidity of mega bracedframe structure system more than mega frame structure system, and the sudden change ofrigidity is smaller; Using mega brace to coordinate peripheral column, which improvesanti-pushover performance and anti-shear performance of overall structure; Mega braced framestructure system has better Anti-seismic performance, and mega braced frame with energydissipators structure system with damper has obvious damping effect.
