AISC Steel & Timber Research For High-Rise Residential Buildings

This research study investigated structural steel frames with timber floors for use in high-rise residential buildings. SOM engaged with the American Institute of Steel Construction (AISC) for this study. The study is an application of the findings revealed in the OSU testing report. The proposed structural system combines shallow steel framing and a composite CLT and concrete floor system, which maximizes the advantages of each material. Structural steel framing is provided for its superior spanning capabilities and the composite timber floor system is provided for its lightweight properties. The resulting combination is able to achieve column bay sizes consistent with flat plate concrete construction and a flat soffit condition.
