| In addition to the protection of the cultural heritage of ancient Chinese architectureand inheritance, how to create an archaize building with Chinese style and geographicalfeatures for the current urban development and construction is of great significance. Atpresent, China's many regions and cities have built a lot of archaize building, butantique and modern building is very different from the stress mechanism because of thedifference of the material structure. Lanna amount and column of archaize buildingform dual beam-column joints; the joints form is different from general joints. Fourbeam-column joints based on a scenic Xi'an engineering example were designed andwere low cyclic tests and finite element analysis and parameter validation.In this paper,two side joints and two mid-joints of dual beam-column joints of the archaize buildingare designed and produced, considering the influence of different axial compressionratio, different nodes form of seismic performance of all-welled rigid dual beam-columnjoints of the archaize building. The experiments research is carried out under low cyclereversed loading. Meanwhile the hysteresis loops and skeleton curve are also given. Thefailure pattern, deformation characteristics, hysteresis behavior, ultimate load, rigidityand energy dissipation are studied. And rational designs suggestions are put forward.By ABAQUS finite element, the contact relationship was used to build the refinedfinite element model of all-welded rigid dual beam-column joints of the archaizebuilding, and the simulation results and experimental results obtained in the hysteresisloops and failure modes were compared, and correctness of the model was verified. Onthe basis of this model, the influence of different parameters on the seismic performanceof structures was analyzed. The results show that the refined model can be used tosimulate all-welded rigid dual beam-column joints of the archaize building; the resultsobtained by the finite element analysis can be used to provide reference for seismic evaluation and theoretical analysis of all-welded rigid dual beam-column joints of thearchaize building. |
