Paper Guiding Applications of Steel-Plate Shear Walls Wins Reese Prize

May 3, 2016


Ronny Purba, Ph.D., and Michel Bruneau, Ph.D., P.Eng., F.ASCE, are this year’s recipients of the ASCE Raymond C. Reese Research Prize for their paper “Seismic Performance of Steel Plate Shear Walls Considering Two Different Design Philosophies of Infill Plates. II: Assessment of Collapse Potential,” which appeared in the June 2015 edition of Journal of Structural Engineering.

Established in 1970, the Reese Prize is awarded to the author or authors of a paper that describes a notable achievement in research related to structural engineering.

The duo’s paper is the only one to date that has investigated the  consequences on seismic performance of designing steel-plate shear walls relying or not on the infill plate to resist all story shears, and has done so using state-of-the-art tools and a rigorous approach. The paper concludes with specific design recommendations for changes to the AISC seismic design provisions. Read the abstract for the paper in ASCE Library.

One critical aspect in the design of these steel-plate shear walls is how much of the story forces should be resisted by the infill part of the wall. There is much disagreement in the literature on this topic, but, until now, no research substantiated any of the number often recommended for design. Values assumed have a direct and major impact on the cost of these walls.

Purba’s and Bruneau’s recommended design changes have been implemented in the document that directly governs the design practice. As such, this paper has all the desired attributes for the ASCE Raymond C. Reese Prize, which is to be “awarded to the authors of a paper that describes a notable achievement related to structural engineering research” and, most importantly, “which indicates how the results of research can be applied to design.”
