Research Overview
Steel and composite steel/concrete structures; earthquake engineering; structural stability; large-scale experimental testing of structures; regional simulation
Laboratory for Structural Testing of Resilient and Sustainable Systems
The double-height STReSS Lab features a 2,000 square-foot, reinforced concrete strong floor to enable full-scale testing of buildings, bridges, and other structures to failure. The strong floor includes a grid of 416 tie-down anchors, each capable of withstanding 200,000 pounds of force.

Broad Experience Made the Difference
Aravind Uthaman, ME’19, civil engineering, was crawling on his hands and knees for more than 300 feet into a water conduit tunnel. It was certainly not a position he expected to be in when graduated in 2019 with a master’s degree in structural engineering. But then again, Northeastern students pride themselves on being able to […]
