摘　　要：由于环境与人为等因素的长期影响,木结构古建筑普遍存在倾斜歪闪等损伤问题,严重影响了古木建筑的安全,亟需纠偏修复。研究尝试提出一种整体纠偏方法,构建木构架结构纠偏理论计算模型,通过数值模拟方法分析了纠偏过程的可行性,并以某多层木结构建筑的纠偏复位过程为例加以验证。结果表明:纠偏后结构楼层偏移明显减小,纠偏过程中主要结构构件仍然处于弹性范围内,纠偏效果良好,可为同类古建木构架纠偏理论研究提供借鉴。Due to the long-term influence of environmental and man-made factors,the ancient timber buildings generally have damage problems such as tilt and flicker,which seriously affect the safety of ancient timber buildings and urgently need to be corrected and repaired.This study attempted to propose an overall correction method,constructed a theoretical calculation model of wood frame structure correction.The feasibility of the correction process was analyzed by numerical simulation method,and the correction and reset process of a multi-story wood structure building was taken as an example to verify.The results show that the deviation of the structural floor is obviously reduced after correction,and the main structural components are still in the elastic range during the correction process.The correction effect is good,which can provide reference for the correction theory research of similar ancient timber frames.
