Normal fault earthquakes or graviquakes [PDF]

open access: yes, 2015
Earthquakes are dissipation of energy throughout elastic waves. Canonically is the elastic energy accumulated during the interseismic period. However, in crustal extensional settings, gravity is the main energy source for hangingwall fault collapsing ...

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Stress transfer and strain rate variations during the seismic cycle [PDF]

open access: yes, 2004
The balance of forces implies stress transfers during the seismic cycle between the elastobrittle upper crust and the viscoelastic lower crust. This could induce observable time variations of crustal straining in the interseismic period.

Experimental analysis of bolted connections for precast concrete walls under cyclic tensile loading

open access: yesStructural Concrete, EarlyView.
Abstract Dry‐bolted connections in precast wall structures simplify the assembly process and offer significant advantages in terms of construction speed and cost. In fact, the reduction of the required workmanship, compared to wet connections, makes this solution highly competitive.

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Influence of seismic events on shallow geotechnical structures [PDF]

open access: yes, 2017
This paper deals with a summary of possible seismic loading of shallow geotechnical structures. It is known that seismic loading influences the underground structures much less than the structures on the surface, therefore, it is not usually taken into ...

Heterogeneous coupling of the Sumatran megathrust constrained by geodetic and paleogeodetic measurements [PDF]

open access: yes, 2008
Geodetic and paleogeodetic measurements of interseismic strain above the Sumatran portion of the Sunda subduction zone reveal a heterogeneous pattern of coupling.

Geodetic observations of post-seismic transients in the context of the earthquake deformation cycle

open access: yesComptes Rendus. Géoscience, 2006
Satellite geodetic techniques that can measure displacements with millimeter-level accuracy reveal transient signals in the deformation fields produced by both moderate and large earthquakes. These post-seismic signals exhibit characteristic time scales ranging from weeks to decades and distance scales from hundreds of meters to hundreds of kilometers.

TRM‐to‐concrete interface bond without anchors: Combined experimental, analytical, and numerical modeling approach

open access: yesStructural Concrete, EarlyView.
Abstract Textile reinforced mortar (TRM) systems have emerged as an effective alternative to conventional FRP strengthening solutions due to their compatibility with concrete substrates and favorable performance under adverse environmental conditions.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

open access: yesWildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.
