Nonlinear Wind Design of Steel Reinforced Concrete (SRC) Coupling Beams
Nonlinear Wind Design of Steel Reinforced Concrete (SRC) Coupling Beams
This research will characterize the nonlinear response of steel reinforced concrete (SRC) coupling beams under wind demands. SRC coupling beams, an alternative to rebar-reinforced concrete coupling beams, reduce reinforcement congestion in the coupled walls and simplify construction. Current design guidelines for SRC coupling beams consider nonlinear response to seismic demands. 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. There is an industry need to address this research gap in order to design for modest coupling beam nonlinearity using the ASCE/SEI Prestandard for Performance Based Wind Design (ASCE, 2019). This is a companion effort to RGA #05-19, Steel Coupling Beams in Low-Seismic and Wind Applications
