Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

Structural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Probabilistic Seismic Hazard Assessment of Lisbon (Portugal)

GeoHazards
The 1755 Lisbon earthquake holds significant historical importance in Portuguese history. The subsequent tsunami resulted in extensive destruction and damage, affecting not only Lisbon but also other regions of Portugal, Spain, and North Africa.

Seismic hazard assessment of Navarre (Northern Spain) [PDF]

, 2008
The RISNAV project, financed by the Civil Defence Department of Navarre (Northern Spain), aims at assessing seismic risk of the entire region. The final goal of the project is the definition of emergency plans for future earthquakes.

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

Structural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

Structural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.

The contribution of source parameter estimations and ground motion simulations in integrating input data for seismic hazard assessment: an application to the volcanic island of Ischia (Italy)

On 21 August 2017, a M w 3.9 earthquake struck the island of Ischia, causing two casualties and significant damage in the village of Casamicciola Terme and its surroundings. The earthquake was recorded by the local INGV-OV seismic network, and represents

Damping ratio of reinforced concrete walls under limited damage from shaking table test and data‐driven modeling

Structural Concrete, EarlyView.
Abstract Accurate estimation of the damping ratio is critical for evaluating floor response spectra and equipment seismic demands in nuclear power plant structures. This study investigates the elastic damping ratio of reinforced concrete walls under limited damage states through shaking table tests and data‐driven modeling.

Why wolves walk – drivers of daily movement in a social large carnivore

Wildlife Biology, EarlyView.
Animal movement patterns are influenced by a range of extrinsic and intrinsic factors, including the distribution of resources, human disturbance, landscape connectivity, species interactions, and individual traits. We examined factors associated with daily movement distance (DMD) and linearity in 20 territorial Scandinavian wolves Canis lupus during ...

Playing with fire: Wolf response to active wildfires, fire fronts and smoke

Journal of Animal Ecology, EarlyView.
This study is one of the first, to our knowledge, to explicitly examine fine‐scale behavioural responses of a large carnivore to actively burning wildfires, fire fronts and smoke. The study found that wolves balanced the potential risks and benefits associated with wildfires, with implications for predator–prey dynamics in fire‐prone regions.
