Nonlinear Wind Design of Steel Reinforced Concrete Coupling Beams

This research looks to determine the nonlinear response of steel reinforced concrete (SRC) coupling beams under wind demands. Current design guidelines for SRC coupling beams consider nonlinear response to seismic demands, but there is a lack of research on the behavior and residual deformation capacity of SRC coupling beams subjected to many loading cycles at modest peak ductility demands. This research will support the design for modest coupling beam nonlinearity using the ASCE/SEI Prestandard for Performance Based Wind Design (ASCE, 2019).
