Falling Simulation Of The Energy Dissipation Corridor On Connected Twin-tower Subject To Near-fault Multi-dimensional Seismic

As the urban population, resources, environment, transportation and many otherproblem arises, and the acceleration of urbanization, high-rise buildings with all kindsof different function comprehensive together have developed rapidly both at homeand abroad. Twin–tower connected high-rise building with enlarged base structure isone than a common. This structure not only grand and architectural appearancebeautiful, but also has the advantage of covering small and plot ratio higher and otherremarkable economic benefits, so it get the favor of a lot of architects. But becausethe existence of the corridors made the stress state between the corridors and towersvery complex, so the corridors may easily dropped under earthquake, earthquakedisaster in domestic and foreign have all proved this. However, the flexibilityconnection using energy dissipation device can improve the ability of structure toagainst the earthquake. But when the structure is located in the near-fault area orsubjected a strong earthquake, the energy dissipation corridors may produced largedisplacement, this will lead to the damage of the corridors. The researches on thisaspect are relatively few at present. So, in order to study the damage mode of thecorridors, it is necessary to conduct the falling simulation of the corridors whichsubjected to the near-fault seismic wave. This paper contains the following parts.1. Introduce the background and the significance of the research, thansummarized the relative research of the near-fault seismic, multi-dimensionearthquake and the connected high-rise structure.2. Using the finite element software MSC.MARC which has strong nonlinearanalysis function, build up the analysis model of the symmetry and asymmetryconnected structure, than dynamic property of the connected structure with energydissipation device on it is conducted, and comparative analysis of the dynamicproperty under the different connection modes is processed finally.3. Elastic time history analysis of the connected twin tower with energydissipation device is processed firstly, than comparative analysis is carried onnear-fault seismic and far field seismic as well as different connection modesrespectively, from the above, the influence of the near-fault seismic and the change ofthe connection can be inferred.4. By conducting the drop simulation analysis of the energy dissipation corridorsunder the seismic, studied the damage mechanism of the corridors, and the result can be referenced by the engineering design.
