Seismic Performance Analysis and Design of a Mega Structure with Buckling Restraining Braces under Super-strong Earthquake
To study the vibration control effect of the mega structure with buckling restraining brace(BRB)
a 48-story mega frame structure was designed with SAP2000
under the requirements for Intensity 8fortification against earthquakes.And then
all the braces of the mega structure were replaced by BRBs whose stiffness are equal to common braces or BRBs whose area are equal to common braces
respectively.The two updated structures are referred to as the EKBRB structure or EABRB structure.Finally
elastoplastic time history analysis of the three structures were conducted under Intensities 8
8.5and 9earthquake.The results show that interstory drift ratio of BRB structure is significantly reduced and changes more uniformly under Intensity 8earthquake compared to the mega structure;the BRB structure meets the seismic fortification target that repairable under severe earthquake and no-collapse under super-strong earthquake.Thus it can be seen that the BRB structure provides enough emergency capacity for structures.
