The Amazing Adventures of Archibald Esq.
The Genius of Dog Bone Joint Engineering
As a regular reader of my humble dog blog pages, you are likely to know that doggish references pop up in the most diverse number of places. Dogs and hounds have crept their way into the whole of human life, from art, culture, literature, song, dance, and also - as in this instance - architecture.
So it won’t surprise intrepid readers to learn that there is not only such a thing as ‘Dog Bone Joints’ used in construction, but also that Dog Bone Joints are said to be better as weight-bearing support beam joints.
Balant & Yang’s research article — Post-northridge earthquake seismic steel moment connections – deals with Dog Bone engineering techniques. Their abstract states: “After the 1994 Northridge earthquake a tremendous amount of research activity was generated in the United States. In this paper on introducing the basic concepts of seismic design, and illustrating a typical pre-Northridge earthquake steel connection, the fundamental reasons of the poor behavior of the connections are discussed. Then the development of the so-called Dog Bone connection is brought in. Experimental results on two connections of this type are discussed in detail. The reasons for good behavior of Dog Bone connections are then explained using three-dimensional von Mises yield criterion. This new analytical demonstration provides solid evidence as to why the Dog Bone connections behave well. Actually, ‘dog bone’ design in engineering is widespread, involving a range of materials from iron, steel beam to rubber.
Indeed, Dog Bone engineering may be crucial in earthquake-resistant architecture. As such - in this turbulent and increasingly seismically unstable world we live in - dog bone engineering may very well be the wave of the future.
Superwoof to well-behaved dog bone joints!

I must apologise to all my houndish pals for the long gap in dog blog posts. My private secretary has been taking some time off. I’ve told little feet in all seriousness that she is in danger of redundancy if she doesn’t get to posting new images and keeping up-to-date with newshound and dog tale posts. I’ll keep you posted, but in the meantime if any of you out there would like to pen an occasional dog blog article, please feel free to fill in a feedbark form.
