| Huishan Temple is one of the representative buildings of the “Heaven and Earth” historical buildings in Lushan,Henan Province.It was declared a national key cultural relics protection unit in 1996 and was later listed as a World Cultural Heritage in 2010.The main hall of Huishan Temple is the main building of Huishan Temple.It is one of the rare examples of the Yuan Dynasty’s physical architecture.It has a high artistic and scientific value in the history of architecture.At present,there is less scientific research on the struggles of the Yuan Dynasty.The research on the Huishan Temple is concentrated on the architectural form and cultural characteristics.The scientific research on the structural mechanical properties is rarely involved.The bucket is located between the roof and the beam and is one of the important parts of the wooden structure.Due to the change of natural climate,earthquake,long-term disrepair,wood aging,etc.,some components of the temple of Huishan Temple have been destroyed,cracked,dislocated and destroyed,which seriously affected the safety of the temple of Huishan Temple.The ability to use and resist earthquake disasters.In order to ensure the safety performance and sustainability of the overall structure of the main hall,Zhengzhou World Heritage Center conducted a detailed investigation and research on the status quo and disease status of the Huishan Temple Hall,and carried out structural safety dynamic monitoring.Relying on the Zhengzhou World Heritage Center Project-"The Status Quo of the Historical Buildings in the Heaven and Earth",Disease Investigation and Database Construction(20160220A),taking the battle between the pillars of the Huishan Temple and the pillars of the temple,the full scale model is carried out.The vertical static loading and horizontal quasi-static loading test research provide data support for the safety dynamic monitoring and database construction of the later hall structure and provide scientific basis for the study of the Yuan Dynasty.This paper specifically completes the following related work:1 Through the field measurement of the Daxiong Temple in Huishan Temple and the compilation of relevant historical data,the data of the dimensions and material parameters of the halls of the hall were obtained,which provided basic information for the later model making,and introduced the structure of other buckets in the hall.Features.2 A monotonic vertical static loading test was carried out on the full-scale model of the two pillars of the Daxiong Temple in Huishan Temple.The deformation and force mechanism of the bucket specimen under vertical load are discussed.The theoretical calculation model of vertical stiffness is obtained.The results show that under the vertical load,the interaction between the bucket and the head and the muddy raft is prone to shear fracturing damage,which is a weak part of the bucket specimen;the recovery and deformation ability of the bucket is poor,and there is residual deformation at the end of the unloading.(Z01: 23.4mm,Z02: 19.3mm);in the test,the bucket has good vertical bearing capacity(Z01: 384 kN,47.7mm,Z02: 382 kN,42.2mm);the peak deformation of the bucket is: head The largest is the second,the second is the second,the grasshopper head is the smallest;the vertical ductility coefficient of the specimen is better,indicating that the bucket has a certain deformation ability under the vertical load;the strain order of different members after the test is loaded to a certain extent For: the muddy raft is the largest,the melon seeds are the second,and the raft is the smallest.Under the vertical load,the internal force shared by the bucket,the head ang,and the mud raft member is the largest,and the internal force of the upper member is smaller;under the vertical load,The vertical stiffness calculation model of the bucket can be simplified to a three-fold line segment model.3 The X-direction horizontal quasi-static loading test was carried out on the full-scale model of the two pillars between the two main columns of the Huishan Temple.The failure mode and seismic performance of the bucket X under the reciprocating load are analyzed.The parameters such as bearing capacity,stiffness degradation,ductility coefficient,strength degradation and energy dissipation capacity of the bucket are discussed.The results show that the main forms of damage are cracks and dislocations,and the bucket is the weakest part of the whole bucket,which is prone to fold and fracturing damage.During the lateral deformation of the bucket in the X direction,the components are There is a certain frictional slip and shearing effect.The movement of the bucket when the control displacement is small is mainly the extrusion deformation.As the control displacement increases,the relative friction slip ratio between the components increases;the hysteresis loop saturates,reflecting Fighting has better energy consumption.During the initial loading process,the components of the bucket are tightly squeezed together,and when the bucket is laterally displaced,a large external force is required,and the rigidity value is large.In the later stage of loading,the components of the bucket are in a relatively stable sliding friction state,and the stiffness value is small;the energy consumption of the bucket is mainly frictional slip;the strength of the bucket is rapidly increased at the initial stage of loading,and the medium strength is The decrease is basically stable at the later stage;under the low-cycle repeated load,the X-direction horizontal stiffness calculation model can be simplified to the form of a three-fold line segment.4 A Y-direction horizontal quasi-static loading test was carried out on the full-scale model of the two pillars between the two main columns of the Huishan Temple.The parameters such as bearing capacity,stiffness degradation,ductility coefficient,strength degradation and energy dissipation capacity of the bucket Y in the action of reciprocating load are analyzed.The results show that the damage form is mainly the fold damage of the bucket,the dislocation between the grasshopper head and the scorpion,the horizontal crack of the mud shovel,the head ang,the slow squat;the initial force of the bucket is loaded,the force required is large.The overall performance shows good elasticity and the stiffness value is large.In the later stage of loading,due to the crushing failure of the components of the bucket in the case of large control displacement,the frictional slip of the bucket specimen is obvious,and the stiffness value is reduced;Hours,the energy consumption of the bucket is mainly based on the extrusion and bite between the components.When the control displacement is large,the energy consumption of the bucket is mainly friction slip;the single energy consumption value in the X direction is greater than Y.The energy consumption value of the direction,under the same control displacement,the force required for X loading is less than the Y direction;under the action of low cycle repeated load,the Y-direction horizontal stiffness calculation model of the bucket can be simplified into the form of a three-fold line segment. |
