Composite steel and concrete lateral force resisting systems are not commonly used as the primary
lateral force resisting system in regions of high seismicity. This presentation discusses one particular type of composite steel and concrete lateral force resisting system, the Composite Partially Restrained Moment Frame (C-PRMF). ASCE 7 permits the use of this system in Seismic Design Categories A through D. The moment frame is created by using the composite floor slab and a seat angle attaching the bottom of the steel beam to the steel column. As part of the presentation, a worked example of this system will be shown.

Presenter will be Robert G. Pekelnicky, PE, a principal of Degenkolb Engineers in San Francisco. Pekelnicky specializes in making community and business infrastructure resilient against earthquakes, explosions, and other hazards. He has applied his multi-hazard mitigation knowledge to various projects for government, high technology, and healthcare clients. His career has focused
on taking new, innovative structural engineering concepts from research and applying them to practice
to better meet clients' needs. He is a member of the BSSC Provisions Update Committee and Chair of Project 17's
Acceptable Risk Work Group.
