The Overrun Analysis and Design of an Old Reconstruction Project in Guangzhou
An old reconstruction project has two under-ground floors,including six 48-storey super high-rise res-idential buildings and two 41-storey high-rise residential buildings,which are reinforced concrete shear wall struc-ture system.In view of each overrun item and structural weaknesses of the super high-rise structure,the project has adopted the seismic performance design,and realizes the structural performance objectives through various analyses and improved calculations.Specifically,YJK and MIDAS software are used for comparative analysis of frequently occurred earthquakes,and the results show that the main structural indicators are within the allowable range of the code;the elastic-plastic time-history analysis is carried out by SAUSAGE,and the results show that the structure performs well under the action of rare earthquakes and the energy dissipation mechanism is reasonable;the analysis of floor temperature influence by YJK software shows that the temperature stress should be considered in the rein-forcement of basement floor with large bottom slab.
