Force-Based Design Method for Force-Limiting Deformable Connections in Earthquake-Resistant Buildings

This paper proposes a force-based design method for force-limiting deformable connections that are used to transfer seismic-induced horizontal forces from the floor diaphragms in buildings vertical elements of lateral seismic force–resisting systems with base flexural mechanisms (e.g., reinforced concrete shear walls). The determines limiting at each building. which transition linear-elastic post-elastic response. Design examples presented. Seismic responses numerical simulations 12-, 8-, and 4-story wall example show proposed enables effective preliminary connections. It is shown designed have relatively uniform distribution connection deformation demands over building height. also their force acceleration reduced magnitude variability compared conventional exhibit large responses.
