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.

Simplified analysis of concentrically loaded reinforced concrete columns

Structural Concrete, EarlyView.
Abstract Reinforced concrete columns subjected to concentric and eccentric compression loads are typically treated in an identical manner, taking into account both the imperfect shape, creep, and the second order effects, as described for example in fib Model Code 2020 and Eurocode 2.

Localized tension characterization of reinforced concrete flexural members using surface bonded distributed fiber optic sensors

Structural Concrete, EarlyView.
Abstract Structural monitoring and assessment can be used to ensure the long‐term performance of structures and inform when maintenance is required by accounting for the degradation of material properties. A key force‐resisting mechanism in reinforced concrete that must be considered as part of an assessment and that can degrade over time is tension ...

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 ...

Strengthening of punching shear of flat slab–column connections through hybrid near‐surface mounted and externally bonded systems: Experimental, numerical, and analytical study

Structural Concrete, EarlyView.
Abstract Slab–column connections are vulnerable to punching shear, particularly when flexural cracking reduces the effective depth. This study proposes a sustainable dual‐strengthening system to enhance punching resistance and combined flexural–punching performance.

Bond behavior of corroded reinforcement: Experimental investigation and finite element analysis

Structural Concrete, EarlyView.
Abstract This study investigates the bond behavior of corroded reinforcing bars in reinforced concrete members using beam tests that reproduce stress conditions representative of structural members, complemented by nonlinear finite element (FE) analysis.

Supporting Young Foreign Language Learners With Image Generative AI in Digital Multimodal Composing: Benefits and Challenges

TESOL Quarterly, EarlyView.
Abstract Integrating generative artificial intelligence (GenAI) into digital multimodal composing (DMC) offers promising avenues for young Foreign Language (FL) learners' learning experiences. Image‐based GenAI tools enable students to generate personalized images from written prompts to help convey meanings, and DMC combines text, images, and sound to
