CEE research featured in new article in Structure magazine

Structure magazine recently published an article titled, “Lincoln Square Expansion,” that explains how steel fiber reinforced concrete solves seismic design challenges.| Short Read

The article is about the Lincoln Square Expansion (LSE) in Bellevue, Washington. According to the article, “LSE is an excellent example of how innovative structural design can respond to high seismic requirements and still meet demanding architectural programs.”

“For the LSE seismic system,” the article continues, “performance based design provided a means to implement steel fiber reinforced concrete (SFRC) in 341 of 392 total coupling beams. This is significant, since the use of SFRC for seismic design has heretofore been limited.”

The article continues: “The study of SFRC started at the University of Michigan, with financial support from the National Science Foundation… The studies concluded that SFRC coupling beams without diagonal bars achieve similar or better performance, compared to prescriptively designed beams. With SFRC, the stiffness, strength and ductility of coupling beams is maintained, even though a significant quantity of reinforcing steel – including the diagonal bars – is eliminated. Use of SFRC in coupling beams can result in up to a 40 percent reduction in reinforcing and 30 percent net cost savings, compared to traditional coupling beam construction.”

The preceding paragraph is referencing research conducted by Professor James Wight and former CEE Professor Gustavo Parra-Montesinos.
