Research On Mechanical Property Of New Concrete Lintel-column Subassemblage In Chinese Traditional Style Buildings

As the functions of architectural construction system become more complicated than before,a variety of different styles were introduced to flatter different needs under new materials,new technology,new technology are widely used in the architectural field and esthetic idea changed,which lead to the architectural form and style of structure have changed drastically over the past many years.How to pass on and carry on traditional Chinese architectural culture in the the tide of history is a problem that deserves our full attention.As a new discovery of the application study on the Chinese ancient structure,Chinese traditional style buildings comes into being.The Chinese ancient architecture is artistic and the cultural marriage was cultural and artistic concrete manifestation,as a carrier of Chinese traditional culture,Chinese ancient buildings show the rich and profound cultural connotations primarily by layout,environment,materials and art,which are exploration and innovation of highly popularized and application in the the future city orientation and development tacticIn order to research the concrete lintel-column subassemblage in Chinese traditional style buildings,2 specimens were tested under dynamic experiment.The failure process and patterns were obtained.The failure characteristics,skeleton curves,mechanical behavior such as the load-displacement hysteretic loops,load carrying capacity,degradation of strength and stiffness,ductility and energy dissipation of the subassemblages were analyzed.The results indicate that compared with lintel-column subassemblages,loading capacity and energy dissipation of traditional style buildings with dual lintel-column subassemblages are higher,and the hysteretic loops is in plump-shape.However,the displacement ductility coefficient is little less than lintel-column subassemblages.Both of them of the regularity of rigidity degeneration are basically the same.Generally,the subassemblages have good energy dissipation capacity.And the concrete lintel-column subassemblage in traditional style buildings exhibit excellent seismic behavior.The numerical simulation results show that: with the increment of the concrete strength,beams spacing,the horizontal load-bearing capacity of the structure is improved;the load-bearing capacity is improved,but the ductility is decreased with the increment of the axial compression ratio.With the increment of concrete strength,the ductility is decreased.The influence of experimental parameters on the load capacity of the concrete lintel-column joint in Chinese traditional style buildings has been calculated by grey system theory method,the influential order of the parameter s is established.The analysis result indicates that the influential order on the load capacity from large to small is the concrete strength,stirrup ratio,shape steel strength and the axial compression ratio.A new kind of lintel-column subassemblage form is formed by combine viscous damper and the traditional style structures.In order to research the traditional style structures with lintel-column subassemblage,4 specimens were tested under dynamic experimental.The failure process and patterns were obtained.The failure characteristics,skeleton curves,mechanical behavior such as the load-displacement hysteretic loops,load carrying capacity,degradation of strength and rigidity,ductility and energy dissipation of the subassemblages were analyzed.The results indicate that the hysteretic curve of the damping subassemblage is plumper.Meanwhile,the performance of displacement ductility and the ability of energy dissipation are superior non-controlled structure.All this reflects that the seismic performance of lintel-column subassemblage is significantly is superior to contrast structure.The damage models were used to evaluate the structures' whole process damage.The results show that the damage curve of Park-Ang model and Banon model is apply to earthquake damage evolution rule for the concrete lintel-column subassemblage in Chinese traditional style buildings with visocus damper.Parametric analysis of the lintel-column subassemblage was carried out based on the theoretical analysis.The axial compression ratio,concrete strength,placement angle of viscous damper,damping coefficient and damping damping exponent were all considered as analysis parameters.The results show that: the change of axial compression ratio has a great effect on loading capacity of structure.With the increment of the axial compression ratio,the horizontal load-bearing capacity of the structure is decreased,but little use in energy dissipation.with the increment of the concrete strength,damping coefficient and damping damping exponent,the horizontal load-bearing capacity and energy dissipation of the structure is improved.the change of placement angle of viscous damper has a great effect on energy dissipation and damping force.The energy dissipation is good when the angle of viscous and column is 60°.And finally,the design suggestions of Chinese traditional style buildings are given for reference in practical use.Four-line models of skeleton curves and restoring force models are presented based on typical characteristics of specimens,and compared with experimental results.The presented four-line models of skeleton curves agree well with the experimental ones,which clearly indicate the failure process of specimens.Additionally,the hysteretic curves from the presented restoring force model agree well with experimental results.The hysteretic behavior of the concrete lintel-column subassemblage in Chinese traditional style buildings is described better by the four-line restoring force model.The presented restoring force model can be adopted to analyze nonlinear seismic response of the concrete lintel-column subassemblage in Chinese traditional style buildings.According to the academic study and design suggestion of new concrete lintel-column subassemblage in Chinese traditional style buildings,the three-dimensional model of smultiple eave hiped-roof structure with viscous damper has been established.The vibration reduction results of the three-dimensional model of smultiple eave hiped-roof structure with viscous damper were analyzed under inter story shear force,maximum lateral displacement base shear force.The analyzing results show that the seismic behavior of the structure can be improved by with a proper location of viscous damper.Furthemore,damping coefficient of viscous damper be analyzed,The analyzing results show that the better for the damping coefficient may be not.On the basis of practical calculation the damping coefficient of viscous damper can be ensured,Only then can viscous damper and smultiple eave hiped-roof structure were well coordinated to achieve the best effect.
