Analysis of the influence of supplementary reinforcement on the behavior of reinforced‐concrete two‐pile caps subjected to concentric and eccentric loading

Structural Concrete, EarlyView.
Abstract This article examines the behavior of reinforced‐concrete pile caps on two piles under concentric and eccentric loading, with emphasis on the influence of horizontal and vertical supplementary reinforcement on load‐carrying capacity. Although the Strut‐and‐Tie method does not include this reinforcement in the internal equilibrium, it was found

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Energy Flows Balance of Electric‐Heating Interconnected Microgrids Under Grid‐Forming Converter Integration Based on Heterogeneous Graph Convolutional Network

Energy Internet, EarlyView.
ABSTRACT The combination of electric‐heating interconnected microgrids (EHIMs) with grid‐forming converters (GFMCs) offers a highly promising approach to improving energy management within decentralised energy systems. Despite its potential, precisely modelling and analysing energy flow in such systems remains a considerable challenge due to the ...
