Behavior of exterior beam‐column joint reinforced with shape memory alloy

Structural Concrete, EarlyView.
Abstract Beam‐column joints are critical regions in moment‐resisting frames and are particularly susceptible to severe stress concentrations and reinforcement congestion. Conventional design typically relies on dense transverse reinforcement to improve joint performance, resulting in construction difficulties and reinforcement congestion.

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.

A novel seismic connector for precast concrete shear walls

Structural Concrete, EarlyView.
Abstract A critical aspect of the seismic performance of precast concrete walls is the deformation capacity of their connections, which can be limited by premature bar fracture, reinforcement buckling, or cyclic instability. This paper introduces and experimentally validates a new ultra‐ductile connector (UltraDC) that provides reliable force transfer ...

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 ...
