Study on Earthquake Resistant Performance of a Large Span Structure Strengthened with HADAS
After the "5.12 wenchuan" earthquake, the fortification intensity of part of the affected areas has adjusted, most of the structures especially the Public buildings need to reinforcement after the fortification intensity was adjusted. In this paper, based on a sports teaching training center which is building when the earthquake happening, with the particularity of the fortification intensity increased, evaluated the seismic performance of the structure before and after fortification intensity increased, and dynamic analysis on the finite element model of different HADAS reinforcement schemes has been done, then evaluated the shock absorption effect under different reinforcement schemes. The results show that: 1) HADAS has important role to adjust the vertical stiffness, enhance the capability of energy consumption, and improve the damping performance of structure; 2) HADAS should decorate in the layer which has larger inter-story displacement angle, that is the neighboring story of stiffness changes greatly; 3) the number and arrangement mode of the HADAS has optimal solution and so on.
