Seismic Evaluation of HSS Column Splices

June 28, 2019

Project included development of a bi-directional loading system to apply simultaneous axial and lateral loading to 6 in. diameter columns and splice connections. Nearly 60 full-scale tests were conducted to support evaluation of a new structural building system for seismic applications. Accredited testing performed to ISO/IEC 17025 standard following protocols provided by FEMA 461.
