Abstract: Based on the researches that how to realize the Pushover analysis for prestressed frame, the way to simulate the prestressed beam in Pushover on prestressed frame-core tube structure was introduced. Meanwhile, its rationality was proved through the contrast of the M-Ф curve of the prestressed beam. Used of Response-2000 and MIDAS on the frame-core tube structure with bonded prestressed for Pushover analysis. Results were believed to be reasonable.
Keywords: prestressed frame-core tube structure; Pushover analysis
