The Study Of The Irregular Seismic Performance For Dalian Castle Hotel

Gradually increased with the complex size and the irregular structure of the high-risebuilding，The irregular structure Body building has become a kind of architecturaltrends.However， a large number of earthquake damage showed that.Irregular structuresin earthquake damage is more severe compared to the regular structure of irregularstructures in earthquake damage than regular structure is more serious.Structuralarrangement can not meet uniform rules， the symmetry requirements, structuralvibration in addition to translational vibration Also accompanied by torsional vibration.In view of the complexity of the structural system of Dalian Castle Hotel， aninternationally well-known large-scale general-purpose finite element structural analysisprogram ADINA analysis of the dynamic characteristics and dynamic response.Theresearch was this structure7degrees case to7degrees in the earthquake under theNatural Frequencies essentially unchanged. the structure in the elastic stage；7degreesboosted the role of the structural natural frequency declined to meet the specifications ofthe elastic-plastic deformation. maximum story displacement angle requirements；8degrees boosted the role of the structure of local concrete cracking and crushingphenomenon，but still be able to maintain the state of the structure does not collapse.Theresearch results show that the structure meets the minor earthquake， earthquake repair,earthquake does not fall seismic requirements.The paper first introduces the relevant provisions of national norms for the irregularstructure defined seismic design. Through the analysis ofStructural vibration treatmentmethod described for the irregular structure factors should consider the impact of theearthquake and the Chinese seismic code.finite element analysis software， thetheoretical basis of the nonlinear analysis of reinforced concrete structures，DalianCastle Hotel project examples to create three-dimensional finite element model, appliedloads，input of seismic waves series of studies in the theoretical basis of the ADINAfinite element analysis software for nonlinear analysis of reinforced concrete structures，Arrive at the structural system to resist earthquake has strong advantages put forwardvaluable suggestions for the design of future similar structure.
