Analysis Of Passive Energy Dissipation Mechanism Of Characteristics In Chinese Ancient Timber Building Of Component

Many modern academic achievements are based on the theory of mechanics of materials and structural mechanics study of ancient artifacts in the static aspect,there are also some experimental study on individual buildings and structures is studied,the parameters of the influencing factors and from the tectonic system of ancient architecture and components of ancient buildings damping energy consumption analysis research is less.Based on hall type structure as an example,this paper study hall type of ancient artifacts(spread a layer,layer roof beams and the column)to the influence of damping energy consumption structure,using the finite element simulation software ANSYS is analyzed.A few finite element models of the different kinds of arches,different column materials and different quality of roof.Separately on model two levels of seismic wave,and the modal analysis and dynamic time history analysis,model,internal force and displacement and acceleration frequency,to the final calculation data and analysis of time history curves are obtained with a layer,pillar and the roof beams of palace type wooden buildings energy consumption the effect of shock absorption,and the following conclusions.Under horizontal earthquake action,the stone of the hop count to the hall type wooden building energy consumption has distinct effect on the damping effect,the hop count,the more the structure of the damping effect,the more obvious energy consumption;The more"soft" structure,the stronger the ability to use earthquake energy,the more noticeable the shock effect.Under the precondition of structure construction,the effect of earthquake effect on the structure of wood structure can be reduced by increasing the quality of the roof.So,in modern architecture,can be set in the beam-column joints appropriate similar stone structure of a class,to help increase structural damping capacity of energy consumption,so as to reduce the level of the destructive force of the earthquake action of building;In order to ensure the safety of the structure,some flexible materials can be used in the important parts of the structure to increase the energy dissipation capacity of the structure and achieve the shock effect.This article has demonstrated the principle of "using the soft gram" in preventing earthquakes.Further illustrate,both ancient building reinforcement and the current seismic design of buildings and prevention,the structural safety under the premise of the important parts adopt flexible better quality materials or reasonable selection of bearing structure can better achieve the purpose of structural damping energy consumption.
