Theoretical and experimental behaviour of a hybrid semi-rigid glulam beam-to-column connection with top and seat angles

Abstract

This article proposes to use the bolted top and seat angles to provide excellent moment resistance and high energy dissipation capacity for glulam beam-to-column connection. Angles are anchored on the glulam beam using the glued-in steel plate technology and connected to the column by anchorage bolts. A theoretical model is presented in this article to evaluate the moment-resistant properties of the connection based on the component method. To validate the accuracy of the theoretical model, several hybrid connections are tested under monotonic and reversed cyclic load. The test results showed that the proposed hybrid connection has a high rotational stiffness and excellent moment resistance. The theoretical results are also consistent with those of the experimental model.

“…The component method is the preferred design theory for these semirigid beam-to-column connections at room temperature [18][19][20] and elevated temperature. [21,22] It divides the joint into several components, such as angles under tension and bending column flanges.…”
