Abstract:The project design and second step design of Nanchang Lianfa Square Office Building are introduced, including the elastic analysis, elasticity and plasticity analysis, the function design, the possibility argument and the examination of the exceed limit design. The analysis of the calculating indicates that under wind load and earthquake load, the main structure of the project has good load bearing capacity and deformability and meets the demand of comfort,and the vertical rigidity is symmetrical and there are no obvious weak layers.
Keywords:height exceed limit; aseismic measure; elastic and plastic analysis; function design; medium earthquake elasticity
