Analysis on performance of reinforced concrete frame structure with steel-bracing based on ETABS
DAI Hong - jun,QI Ai (College of Civil Engineering,Fuzhou University,Fuzhou,Fujian 350108,China)
Computer models of frame with steel - bracing are made,seismic - performance of the models are calcaulated by adopting base - shear method,spectrum analysis,and time history analysis based on ETABS. The results show that including steel - eccens into models will increase story - stiffness,decrease top - point displacement of frame structure significantly,but the base - shear increase a little,reach the require of more defences in seismic concept design of buildings.
