During the one-hour session, Ali Nassiri, Assistant Professor-Research, from The Ohio State University, will discuss his studies of prequalified seismic steel moment connections, where he compared results between IDEA StatiCa, Abaqus, traditional calculations, and experimental studies.

Join the webinar and learn about

Prequalified steel connections after the Northridge earthquake I SAC Steel Projects
Comparisons between IDEA StatiCa and calculations from AISC specification for various common prequalified connections
Comparisons between IDEA StatiCa and results from traditional Finite Element Analysis (FEA) approach
Identifying discrepancies in results and investigating the underlying causes
Summary and future research

Speakers

IDEA StatiCa has engaged several US universities to ensure the application is within the safe threshold of the practical engineering design. This webinar will discuss and review the results of investigation into using Finite element analysis to design steel connections according to AISC 358 prequalified connections. The research was developed by:

Baris Kasapoglu, Ph.D. student (Department of Civil, Environmental and Geodetic Engineering)
Ali Nassiri, Ph.D. (Department of Integrated Systems Engineering)

This project aimed to evaluate the behavior of seismic steel connections obtained from the IDEA StatiCa software package considering load resistance, rotation capacity, and moment-rotation response. The studied prequalified connections were:

Reduced beam section (RBS) moment connection
End plate moment (EPM) connection
Welded unreinforced flange-welded web (WUF-W) moment connection
Welded unreinforced flange-bolted web (WUF-B) moment connection
Double-tee moment connection

Join the webinar session to get the author's insight into the investigation, explanation of the comparisons between IDEA StatiCa and AISC calculations, findings and causes of discrepancies and the future research.
