传统木构建筑螺栓拼合木梁受力机制
Structural mechanism of Chinese traditional timber beams stitched with bolts
摘要
Abstract
In order to study the reliability of repairing method of timber beams stitched with bolts in Chinese traditional timber structures,the research on mechanism of timber beams stitched with bolts was carried out.Structural mechanism of 3-purlin beam model,5-purlin beam model and purlin member model were analyzed based on the traditional repairing method of timber beams stitched with bolts.The position of neutral layers and dangerous points were obtained.The calculation formulae of the shear force,axial force of bolts,and the ultimate bending moment were proposed using material mechanics method.In the end,finite element software ANSYS was used to analyze the structural performance of three types of stitching beam models,and the finite element analysis results were in good agreement with the theoretical analysis.The research results can provide reference for the capacity calculation of stitching timber beams in traditional timber buildings.关键词
