Abstract


High-rise buildings is now more and more widespread adoption of large and medium-sized cities in China , especially for economically developed areas , high-rise buildings for limited land , can well solve many problems such as population live . However , China is also an earthquake-prone area , which to some extent affected the development of high-rise buildings . To solve the above problem , this paper, using the roof structure TMD , especially for high-rise buildings , roof garden TMD , both to increase urban greening , simultaneously to decrease the impact of the earthquake senior . This paper SAP2000 finite element analysis software to analyze this article content analysis including : high-rise building structure without a roof garden as well as a rooftop garden TMD contrast , comparison of the displacement of the structure of the layers , the analysis of the mechanical characteristics of the structure of the roof garden TMD and damping effect . Than the displacement of the structure changes in different situations according to the quality of the roof garden TMD structure to analyze the influence of the mass ratio of TMD damping effect . In different situations according to the rooftop garden TMD damping ratio of the displacement of the structure changes analysis TMD damping than the damping effect of the law . The rooftop garden TMD device structure EL-Centro wave and wave TAFT displacement structural layers between layers and layers shear through the data to identify the structure of the weak layer and view the TMD structure damping can play effect. Study for the roof garden of TMD has a very important practical significance , it can provide important reference to the actual engineering design and construction . Roof garden in addition to be able to play good damping effect , can also be a good increase in the greening of the city and enrich people's lives .
