| To form the architectural modeling of palms together, the Heshi Pagoda of Famen Temple in Shanxi Province used broken barrels as its main vertical component. This structure was a vertical irregular high-rise building. First of all, this dissertation would focus on the special vertical irregular high-rise building and establish the quite sophisticated finite element model of the overall structure with the Ansys program. Secondly, further numerical study on dynamic characteristics, dynamic responses and seismic behavior evaluations of this typical irregular structure would be performed. At the same time, the mechanical characteristics and failure modes of the vertical structures with broken cylinders would be studied. Finally, the reasonableness and the affects of the simplification for the palm and back wall would be studied.This dissertation had carried out some work on the numerical modeling and finite element analysis, structural analysis, seismic performance assessment and the seismic performance analysis of typical skew vertical components.In the linear range, the modal analysis, spectral analysis and dynamic time -history analysis of this structure has been done; In the elastic-plastic range, the nonlinear static analysis for the structure with two kind of lateral load style has been done firstly, and then, the seismic capacity of this structure would be evaluated with the capacity spectrum method.In order to study the elastic-plastic mechanical characteristics of the vertical structures with broken cylinders, this dissertation would focus on three typical walls and choose three phases to examine the development of the stress state.In the shaking table test model, the palm and back wall had been simplified to steel frame. In order to study the affects of this simplification, this dissertation would establish a simplified finite element model of the overall structure and analysis the results of calculation to produce corresponding conclusions. |
