Abstract: A super high-rise office building with the height of 139m is classified as level-B height high-rise building by code and adopts double lateral resistant system of reinforced concrete frame-corewall structure. In alignment with the concept design, The design of the foundation and the base, The select and analysis of the structural type and overall structure parameters were introduced followed by analysis of the calculation results; Elastic-plastic time-history analysis was carried out and technical measures on complicated parts of the project were introduced. Seismic measures were applied correspondingly based on the calculation results. The structure safety could be guaranteed.
Keywords: reinforced concrete frame-corewall structure; double lateral resistant system; elastic-plastic time-history analysis
