摘　　要：为研究在不同的初始安装情况下银锭抱肩榫卯节点抗震性能的影响,试验选用杉木和松木各作了3个银锭抱肩榫卯节点模型,制作安装误差缺陷程度的大小通过节点的紧密程度控制,采用控制卯口宽度,削减榫头宽度的方法来模拟。通过低周反复荷载试验,研究6个银锭抱肩榫卯节点的破坏特征及滞回特性,为今后木结构的制作安装工艺提供参考。In order to study the influence of different wood manufacturing and installation error defects on the seismic performance of silver ingot shoulder tenon joint,three models of silver ingot shoulder tenon joints were selected from fir and pine.The defect degree of manufacturing and installation error is controlled by the tightness of nodes.Use the method of controlling the width of the mouth and reducing the width of the tenon to simulate.Through the low cycle repeated load test,the failure characteristics and hysteresis characteristics of six silver ingot shoulder tenon joints are studied,which provides a reference for the fabrication and installation technology of wood structure in the future.
