Tilted Piles Defy Their Bad Reputation by Stiffening Group Foundations Under Strong Shaking
New three-dimensional simulations show that inclined pile groups grow stiffer under vertical seismic loading than vertical groups, because tilting weakens ...
Buried Rubber Layers Could Shield Buildings From Earthquakes, But Only Up to a Point
A new parametric study shows that a two-to-three-meter geotechnical seismic isolation layer of rubber-soil mixtures offers the best balance of ...
How Earthquake Waves Lose Sync: New Study Tests Coherency Models for Big Structures
A new study in the Bulletin of Earthquake Engineering shows that the choice of spatial coherency model strongly influences soil-structure ...
New Analytical Model Predicts Wall Movement in Ultra-Deep Urban Excavations
Researchers have developed a convergent analytical model that couples shear deformation with layered, displacement-dependent earth pressures, predicting deep excavation wall ...
When Earthquakes Meet Slow Landslides: How Hidden Ground Movement Threatens Bridge Piers
A new numerical study shows that slow-moving landslides fundamentally alter the seismic response of pile-supported bridge piers, underscoring the need ...
Water Erodes the Hidden Glue Holding Tunnel Repairs Together, Study Finds
New direct shear experiments show that water immersion strips up to 35 percent of the bond strength between polymer-stabilized soil ...
