Pushover Analysis of Eccentric High-Rise Single-Tower Building’s Frame-Shear Wall Structure

Article Preview

High-rise building with podium is a common seen architecture style in China. Nowadays more designers inclined not to separate the main and podium, but this would lead to the eccentric between the center of mass of the tower and base, which may exceed the code requirement when the ratio of offsetting is larger than 20% and cause complicated seismic response. This paper takes an eccentric high-rise frame-shear wall structure of single tower as example, analyze the inelastic performance of this structure under rare earthquake by Pushover method, and point out the weak parts of the position by the distribution and development of plastic hinges.Draw the structure inelastic response indicators in the rare case of earthquakes, and point out the weak parts of the structure of the distribution and development of plastic hinge (region), put forward reasonable proposals for optimizing the structure design.
