摘要:
在中国传统木构建筑中,梁架构件有梁-角背或梁-随梁枋的拼合做法,而檩条构件有檩条-随檩枋的拼合做法.基于传统木构拼合连接作法,对梁-角背或梁-随梁枋的拼合三架梁模型及拼合五架梁模型、檩条-随檩枋的拼合檩条模型进行了力学分析,推导出了常见拼合梁的极限弯矩以及销栓剪力的计算公式,并对拼合梁的极限弯矩及销栓剪力与上下梁的高度比、宽度比、销栓位置关系进行了分析,得出了一些有价值的结论.当销栓先破坏时,销栓破坏时的极限弯矩受销栓位置影响最大,高度比影响次之,宽度比影响最小;木梁破坏时的极限弯矩与销栓位置无关,受高度比和宽度比影响相差不大.当木梁先破坏时,极限弯矩受高度比影响较大,受宽度比和销栓位置影响相对较小.
Abstract:
In Chinese traditional timber buildings, timber beam members are often strengthened by the stitching method of beam-jiaobei or beam-suiliangfang, and timber purlin members are often strengthened by the stitching method of purlin-suilinfang. Considering the stitching methods in Chinese traditional timber beams, the models of stitching 3-purlin beams and stitching 5-purlin beams using the way of beam-jiaobei or beam-suiliangfang and the model of stitching purlin using the way of purlin-suilinfang are analyzed. The calculation formulae of the shear force of bolt pin and the ultimate bending moment of stitching beam are derived. The relationship between the ultimate bending moment of stitching beam and the shear force of bolt pin and height ratio, width ratio and the location of bolt bin are studied. Consequently, some valuable conclusions are presented. When the bolt pin is broken first, the influence of the location of bolt bin on ultimate bending moment by which the bolt pin breaks is larger than that of height ratio, and the influence of height ratio is larger than that of width ratio. When the timber beam is broken, the location of bolt bin has no influence on ultimate bending moment while height ratio and width ratio have more or less similar influence on ultimate bending moment. When the timber beam is broken first, the influence of height ratio on ultimate bending moment is larger than that of the location of bolt bin and width ratio.
