Design Guideline for Rounded Dovetail Connections
Publication: Structures Congress 2008: Crossing Borders
Abstract
Rounded Dovetail Connections (RDC) are a relatively new method for connecting structural members. The use of RDC in timber construction has significantly increased in Europe, with the most common application being the connection of a joist to a beam or a beam to a girder. A number of experimental studies on RDC provided valuable insight into the structural performance of this versatile connection [Kreuzinger and Spengler, 1999; Blass and Saal, 1999; Hochstrate, 2000; Bobacz, 2002; Tannert and Lam, 2006; Tannert et al., 2007]. The load transfer mechanism of RDC is governed by its geometric features. A revival of interest in timber frame buildings in the United States occurred during the 1970s and since that time, has led to growth in the timber framing industry to keep up with demand for timber frame structures [O'Connell and Smith, 1999] and carpentry connections are being used in a growing number of timber buildings [Schmidt and Scholl, 2000]. But the acceptance of carpentry connections in the North American structural engineering and architectural community is affected by a lack of design values and provisions in building codes [Bamford, 2003]. Engineers and architects indicate that there is a diverse demand and need for guidance in designing connections in wood construction throughout North America, and existing design codes need to be expanded and updated to reflect the acceptance and use of modern wood connections [Snow et al., 2006]. Nevertheless, the Rounded Dovetail Connection is increasingly being used, driving the demand and need for guidance in designing such connections in timber construction throughout North America.
