Elastic-plastic Time History Analysis on the Super-high Business-living Building in Hefei

摘要

This project is a super high-rise office building in Hefei with 128.9 m height. Based on the theory of plastic hinges (beams and columns) and fiber model (walls), elastic-plastic time-history analysis is performed on the super-high business-living building in Hefei by MIDAS Building software under the scarce earthquake load. Failure Modes and plastic zone development are researched according to the feature of the structure. Calculation results indicate that the main building structure has excellent holistic behavior and can meet the seismic performance objective when affected by three rarely earthquake respectively.
