Seismic Analysis On Frame-Tube Structure With Seismic Energy Dissipation Story

Setting strengthened story is a normal method to reducing lateral displacement offrame-tube structure. But it can cause the sudden variation of structural stiffness andinternal forces, and will result in weak story. In this paper, the concept of seismicenergy dissipation story is put forward according to the adverse factors in frame-tubestructure with strengthened story under earthquake action.Firstly, analysis model and methods of seismic energy dissipation structure aresummarized. Then, seismic performance and member forces in frame-tube structurewith strengthened story and different seismic energy dissipation storys are comparedwith response spectrum method and time history analysis method. Workingmechanism of seismic energy dissipation story is analyzed.Secondly, optimal location of seismic energy dissipation story and influence onother performance of different location of seismic energy dissipation story are studiedon the purpose of minimizing top displacement. The influence of belts on seismicperformance of frame-tube structure with strengthened story and seismic energydissipation story are compared.At last, seismic effects of viscous seismic energy dissipation story are analyzedcombine an engineering application. It is found that the structure performance withviscous seismic energy dissipation story is better than strengthened story.Seismic energy dissipation story is the production of combining seismic energydissipation technology and frame-tube structure. It has many virtues, such asdefinitude seismic mechanism, excellent seismic effect and minor influence onbuilding function. Analyzed on seismic energy dissipation story must have a positiveaction on application of seismic energy dissipation technology.
