The Analysis Of The Structure Stability Of Zhongding International Mansion

In this treatise, to use finite element analysis software ANSYS to calculate the flat Lshaped irregular structure named ZHONGDING. To establish the ANSYS model based on thedesign information of the building structure and structural features. Then give a morecomprehensive static analysis and seismic analysis of the construction.The following aspects are mainly work of this paper:(1) Give a good solution to deal with the problem of the size of the shear walls, columnsand floors on the modeling, to achieve a conversion of the plane irregular L-shaped tallbuilding structures to the ANSYS model. An exploratory work is done here.(2)The building model have40,000multiple nodes and60,000multiple units. Its model ismore complex so that we must to do a heavy workload. Give a good solution to the issue of anode coupled in modeling. This is an innovation at ANSYS application.(3) Completed the static analysis with wind load and gravity load case of the building.(4)Give the modal analysis of the structure, and get the self-vibration characteristics andmodes of structure. Do the anti-spectral analysis on the basis of modal analysis, give the resultthat in the earthquake, the diversification of interlaminar displacement and drift angle is veryregular and horizontal displacement gradually increased with increasing storey. At the sametime, to find out parts of the left side of the frame structure which the internal forces larger inthe shear walls roots.(5) By dynamic time-history analysis of three different seismic waves, obtained structuralresponse under different seismic waves. Comparative analysis the layer displacement andInterlaminar angle of structure under the three waves, to find out the maximum shear force atthe central shear wall, providing a basis for seismic design.On the basis of the analysis of the ZHONGDING. From the quantitative correctly reflectthe displacement behavior of plane irregular L-shaped structure. To find out weaknesses in thestructure and made these weak links Retrofitting measures to ensure the normal safe use of thebuilding. The results of the thesis provide the basis for the seismic design of the structure, inChengdu region similar analysis of tall buildings provide a valuable reference views. Especially after the Wen Chuan earthquake, the quantitative safety assessment andRetrofitting of the original construction of the Chengdu region is also very necessary.
