Plan B Engineering’s Post

Completed this year and set to open in 2025, the Studio Museum in Harlem, New York, has undergone significant expansion with the addition of a new building for exhibitions and programming. The central feature in the building’s lobby is a four-story tall monumental steel-framed staircase clad with terrazzo panels, offering visitors views of an 85-foot-tall vertical art gallery. Project architect Cooper Robertson engaged Plan B Engineering to collaborate with Simpson Gumpertz & Heger (SGH) to analyze the staircase’s complex deflection behavior in order to precisely detail the layout of decorative terrazzo panels hung from the steel framework. Our role was to determine the minimum spacing between panels so that the global deflections of the under dead and live loading would not locally cause the panels to come into contact and be damaged. The deflected shape of each cantilevered section of the stairs was carefully reviewed in SAP2000 to ensure that the desired 1/16” panel spacing was acceptable. We also coordinated load testing of select spans to verify the FEA analysis. Special thanks to Kevin Poulin at Simpson Gumpertz & Heger (SGH) for leading the collaboration effort for both this project and the article. We’d also like to acknowledge the team at Sciame Construction, LLC for bringing yet another innovative design into reality.
