Summary
This paper presents the results of an on-going program of the mechanical behaviour of bolted glulam beamto-column connections. The program included testing and modelling of connections of various bolt size, edge distance and lamina alignment patterns. This paper presents part of the obtained results, including monotonic and reversed cyclic loading test results of 10 full-scale beam-to-column connections and the corresponding modelling results. The test results indicated that the perpendicular-to-grain properties of glulam and the localized contact between the bolts and surrounding glulam had significant influence on the stiffness and the maximum moment of the connections. A finite element method based model, which can be easily incorporated in commercial available software packages, was developed and verified based on the test results. Good agreement was achieved. Parametric study results indicated that the tolerance of the bolt holes can significantly affect the mechanical behaviour of the bolted beam-to-column connections.
