Stopping phases mark abrupt arrest in large strike-slip earthquakes
What the study found Large strike-slip earthquakes can show a stopping phase, meaning a pattern in near-field ground motion that marks abrupt rupture arrest. In this study, a transient overshoot in fault-parallel ground surface displacement was identified as a robust sign of rupture stopping. Why the authors say this matters The authors conclude that these…
Injected tie-rods improved out-of-plane masonry wall capacity
Study validates full-length tie-rod retrofitting for reducing out-of-plane seismic vulnerability in unreinforced masonry walls, providing design tools with ~7% accuracy.
Validated single-strut model captures infilled RC frame seismic behavior
Advanced single-strut modeling framework for masonry-infilled RC frames with lightweight infills. Validates material-specific nonlinear hinges for seismic performance assessment with 10% accuracy.
AAC infill improved ductility more than clay infill
Experimental and numerical investigation of RC frames infilled with clay masonry versus autoclaved aerated concrete under cyclic loading, with macromodeling validation.
Masonry buildings showed recurring earthquake damage patterns
Study of masonry building damage from Turkish earthquakes reveals critical failure patterns including out-of-plane wall collapse, poor connections, and material deficiencies. Findings support.
