Shaking Table Test Study Of Traditional Style Building Steel-concrete Frame Consture

As a type of building since modern times,with the development of society,the traditional style of building is more and more favored by the cultural industry,and many traditional style of building that uses the ancient culture as the theme be constructed.The traditional architectural style modeled on the ancient wood building in the form of construction,and there are many differences between modern building and traditional style of building on the form of construction:The differences on form of construction causes the differences on mass distribution,beam column stiffness with modern building.However,the traditional style of the building consture design is not a mature design specifications,and the consture design can only rely on the existing norms of modern architectural design.Based on these reasons that mentioned,it is necessary to study the seismic performance of traditional style buildings.This paper made a steel-concrete frame model of traditional style building with 1:4 scale of the prototype,and this paper did the shaking table test experiment on the model.Recorded the destruction process and destruction mode of model structure during the loading process.Got the acceleration,displacement and strain data of the model structure in Wenchuan earthquake waves of different level,the Lanzhou earthquake waves of different level,the Taft earthquake waves of different level.Based on the data processing,got the dynamic characteristics,hysteretic curve,dynamic lateral stiffness,shear layer data of the structure in the test process.The results show that with the increase of the intensity of the seismic wave,the natural frequency of the structure and the stiffness decrease,and the damping ratio the energy dissipation increase.The acceleration and displacement responses of the model structure increase with the loading and the model of the acceleration amplification coefficient decrease with loading.The frequency of earthquake has huge impact on acceleration response of the structure.The experiment phenomena and strain data shows that ChuanChaFang and YoueLiang damaged firstly,then the concrete column bottom longitudinal reinforcement and corner column of square steel tube yielded.The other parts had no obvious damage in the loading process.When the peak acceleration of earthquake waves is 0.07 g,the model structure is in the elastic stage.When the peak acceleration of earthquake waves is 0.44 g,there is no sign of the collapse of the structure,which meet the " small earthquake earthquake does not result in bad" and "small earthquake earthquake does not result in fall".But in the stage of elastic and elastic-plastic order section,maximum displacement angle model overed the limits,which reflected the lateral stiffness of the structure.Based on the test,this paper made the elastoplastic time history analysis by using SAP2000,and got the acceleration time curve and displacement curves of model structure in different intensity of different types of seismic wave.The comparison of the development and test data are consistent,which verify the rationality of the model.On the basis of the analysis,this paper analyzed the distribution and order of plastic hinge of the model structure under seismic action.
