摘要
In this study, four groups of bolted glulam beam-to-column connections with slotted-in steel plates (in total 22 full-scale specimens) were tested by monotonic and reversed cyclic loading, and a three-dimensional finite element method based model was also developed by using a commercial computer software to investigate the rotational behavior of such connections with consideration of different bolt diameters and edge distances. The test results indicate that a smaller bolt diameter can lead to smaller initial stiffness and maximum moment, and a bigger edge distance can also decrease the initial stiffness. The numerical analysis model exhibits fair agreement with the test results with a modeling error of the initial stiffness and maximum moment less than 20%. A parametric study indicates that the bolt diameter and edge distance have consistent influence on the connection behavior in a wider range of values (the bolt diameter from 12 mm to 28 mm and the edge distance from 30 mm to 70 mm).
