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 ...

High Voltage, EarlyView.ABSTRACT Radiative cooling holds potential for outdoor transformers in operation due to its zero‐energy consumption and high adaptability and has demonstrated effective heat dissipation in simulations of small distribution transformers. Accurate calculation of the transformer temperature rise and the radiative cooling effect is crucial for practical ...

An eddy-current gauge for measuring the wall thickness of light-alloy drill pipes
Russian Journal of Nondestructive Testing, 2017The operating principle and design of an eddy-current transducer intended for in-service measurement of the wall thickness of light-alloy drill pipes are described. The block diagram and algorithm of conversion are provided for measurement-data signals from the eddy-current thickness gauge.

Designing of an Electromagnetic-Acoustic Thickness Gauge for Testing of Thin-Walled Pipes
Russian Journal of Nondestructive Testing, 2002A contactless electromagnetic-acoustic thickness gauge has been designed. The gauge ensures high-rate automatic contactless ultrasonic thickness measurements and makes it possible to process the information in real time, sort out the products into two classes when their thickness deviates from the permissible interval, to display the measurement ...
