摘要
利用有限元分析软件ANSYS,对明代徽派木结构古民居进行地震作用下的抗震性能分析。榫卯节点是半刚性节点,采用弹簧单元作为榫卯节点与各个构件之间的连接单元,模拟榫卯的半刚性连接,进行时程分析,找出受力最大和最小的部位,得出了古民居的动力放大系数,并对徽派木结构古民居抗震性能进行了研究。分析结果表明木结构古民居具有较好的抗震性能,其抗震性能主要是通过构架的变形、摩擦滑移来实现的。
Using finite element analysis software ANSYS,the author analyzed the properties under the seismic action in ancient folk house of Huizhou wooden structure in the Ming Dynasty.In finite element model,assuming the nodes of mortise-tenon joints as semi-rigid unit and adopting spring element as the connecting element between mortise-tenon joints and other components.Then,analyzed the time-history,found out the largest and smallest part of the force and obtained seismic amplification factor,the author also studied the vibration isolation properties in ancient folk house of Huizhou wooden structure.The analysis results showed that the ancient wooden folk house has a good seismic properties.Its seismic properties mainly through framework deformation and friction-sliding to achieve.
