Seismic Behavior of Concrete-Filled Steel Sandwich Walls [N29]

An experimental and analytical research results from an investigation on the CFSP Sandwich wall concept for seismic applications. Research generated critical fundamental knowledge on the flexural cyclic inelastic and seismic behavior and performance of these systems. This testing looked at these walls with and without boundary elements and considered issues related to foundation design for proper load-transfer behavior. Nonlinear detailed finite element models were developed to investigate local response mechanisms and expand the experimental results to include a wider range of parameters to define response. This research work will serve as the basis to develop and validate design recommendations for inclusions in future seismic provisions.
