Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa
Structural Concrete, EarlyView.Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method
Structural Concrete, EarlyView.Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

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.

SEISMIC HAZARD ANALYSIS OF SONDUR DAM SITE OF CHHATTISGARH STATE [PDF]
, 2015 Seismic vulnerability analysis, an approach to get an estimate of the strong ground-motions at any particular site, is mainly intended for earthquake resistant designs or for seismic safety assessments. The hazard analysis usually attempts to analyze two

core
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.

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.

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.

The Newest Federalism and Population Health
The Milbank Quarterly, EarlyView.Policy Points In the United States, social policies at the federal, state, and local levels affect population health. The country is undergoing major changes in its social policies and intergovernmental relations. As both state and local governments have taken different approaches to social policies, where one resides and the socioeconomic resources ...
