Welcome to the Sustainable Structures Group website! Among the most important current engineering challenges is discovering how to maintain standards of living without sacrificing the long-term health of our environment and our society, or, in other words, discovering how to obtain comprehensive and enduring sustainability. Structural engineers have an enormous role to play in this discovery, as the environmental impacts associated with the existing built environment are staggering. Given this vast challenge, the overall intent of this group is to overcome structural obstacles that are emerging as our society evolves towards comprehensive sustainability. I hope you find this website useful. Our latest results are available at the publications page.

First large-scale test completed at the STReSS Lab!

Last month, we completed our first large-scale test at the STReSS lab — see picture below taken from the overhead crane. The specimen was a spirally welded tube manufactured by Keystone Tower Systems and loaded in pure bending. The hydraulic loading and data acquisition systems both worked perfectly. Next test will be in late October. We are currently adding two laser scanning systems to more accurately characterize imperfections and local buckling. You can read an overview of this project here.

New grant with Keystone Tower Systems

The Department of Energy just announced a $1M grant to Keystone Tower Systems with a subaward to Northeastern. The project will provide a detailed design and certification for a spirally-welded tower supporting a utility-scale wind turbine.

New PhD student

Rob Rosa, a 2014 B.S. graduate from UCONN, will be joining the Sustainable Structures Group in early July. Rob will be helping to design and execute our large-scale tests on spirally-welded tubes.

STReSS Lab’s hydraulic actuator system is live

Our hydraulic actuator system at the STReSS lab is fully functional — see below! Our first series of tests is scheduled for July 2014.

I promise that future testing videos posted here will be more exciting than this, but, for now, the best I can do is a video of a slowly moving actuator.

New Test Rig

We just finished the design of our test rig — see below. The rig has been designed to test spirally-welded wind turbine towers in pure bending and bending-compression. Max axial force is 400 kips. Max moment is 1600 kip-ft. Tests are scheduled to start this summer at the STReSS lab in Burlington.

Finally

A mere two and a half years since joining the faculty at Northeastern, I have finally finished my personal research website, or rather, my Ph.D. student’s husband, James Jay, has finished my personal research website :-). Thanks James! The main purpose of this site is to summarize and disseminate my group’s work, however, I soon hope to also provide some useful research tools which we are developing. If you have any questions, please email me at atm@neu.edu.
