摘要

这项工作的目的是研究由全螺纹木螺钉机械连接的两根实木梁的承载能力。将所得结果与相同尺寸的胶合木梁的承载力进行了比较。根据LVS EN 408+A1:2012第9、10和19点进行四点弯曲试验，以确定弹性模量和弯曲强度。根据欧洲规范5的要求，将测试结果与分析计算进行比较。目的是通过比较两束光束的特性来实现的。机械连接实木梁和胶合木梁的主要区别在于，梁的连接降低了弹性模量，同时仍然提供良好的抗弯强度。

Bending properties of mechanically jointed solid timber beams.

The aim of this work is the study of the load bearing capacity of two solid timber beams mechanically jointed by fully threaded timber screws. The obtained results are compared with the load bearing capacity of a glulam beam with the same dimensions. A four-point bending test according to LVS EN 408+A1:2012 points 9, 10 and 19 is performed to determine the modulus of elasticity and the bending strength. The test results are compared to analytical calculations according to Eurocode 5 requirements. The aim is achieved by comparing the characteristics of both beams. The main difference between mechanically jointed solid timber beam and a glulam beam is that joint of the beams reduces the modulus of elasticity while still providing good bending strength.
