NEW RESEARCH REPORT: Steel Coupling Beams in Low-Seismic and Wind Applications
The Charles Pankow Foundation (CPF) in partnership with the Magnusson Klemencic Associates Foundation and American Institute of Steel Construction, are pleased to announce the new research report, Steel Coupling Beams in Low-Seismic and Wind Applications, is available for free download. This product completes CPF Research Grant Agreement #05-19.
This research was conducted at the University of Cincinnati and led by Principal Investigator Bahram Shahrooz with Co-Principal Investigator Rachel Cross and in collaboration with Christopher Motter at Washington State University. Industry Champions included Greg Deierlein, Stanford University; David Field, MKA; Kent Harries, U. of Pittsburgh; John Hooper, MKA; Devin Huber, AISC; Ronald Klemencic, MKA.
The project is dedicated to the memory of Patrick Fortney.
Overview: Coupled structural (shear) walls (CSW) are a common structural system. This system is comprised of two or more structural walls that are linked, typically, at each floor by coupling beams. Based on the expected level of inelastic deformations, composite structural (shear) walls can be classified as Composite Ordinary Shear Wall (COSW) or Composite Special Shear Wall (CSSW). One common composite system involves linking reinforced concrete wall piers by steel (or steel-concrete composite) coupling beams that are embedded in the wall piers. Design and detailing of steel coupling beam-wall connection in COSW was the focus of this research. Results and recomendations can be found in the final report.
