Elastic-plastic Finite Element Analysis Of Huizhou Wooden Structure Ancient Dwellings

Huizhou has a long history and culture with a distinctive unique regional architectural culture.The most distinctive architectural style of Huizhou is ancient houses, still retains the ancient houseswith more than two thousand buildings, known as "Royal Garden north, south ancient houses" said.Huizhou ancient dwellings of wooden structure as the object of study, bases on a typical Anhuistyle form founding a three-dimensional finite element model and its structural system, the variouscomponents of a brief introduction, theoretical analysis of the overall structure and numericalsimulation, it is assumed that the tenon node semi-rigid unit, to determine the stiffness coefficient,spring elements as the tenon joint nodes between the various components of the connection unit, itstime history analysis to identify the force key components or parts explore the vibration in the formof the model to solve the seismic amplification factor of the ancient houses, the wooden structureof the Huizhou ancient dwellings isolation properties were studied. Analysis showed that theancient houses of the wooden structure has better energy consumption and seismic performance.The seismic performance is mainly reflected in the architecture of the deformation, slip friction andvibration isolation on energy consumption. In monotonic displacement loads, stress analysisframework and pull tenon damage, were discussed plasticity, draw the structure of the force in theform and failure modes.
