Subduction and Shallow Earthquake Demand on Coupled Composite Plate Shear Wall–Concrete-Filled System
Publication: Journal of Structural Engineering
Volume 150, Issue 8
Abstract
This brief technical note compares the adjusted collapsed margin ratios for concrete-filled coupled composite plate steel walls, as obtained from the FEMA P695 methodology, separately considering only subduction zone earthquakes and only shallow earthquakes. For shallow earthquakes, collapse margin ratios were similar to those obtained in prior studies, but they were substantially smaller for the set of subduction earthquakes. While both sets of collapse margin ratios were considered to provide satisfactory seismic performance, this study provides insights into the impact of considering subduction earthquakes in FEMA P695 studies and, by inference, on expected collapse margin ratio for subduction earthquakes.
