Inferring cumulative crack widths in reinforced concrete structures using Coda Wave Interferometry of ultrasound

Structural Concrete, EarlyView.
Abstract Whether concrete structures are cracked, how wide these cracks are, and whether they must be regarded as damaging, is a central issue in structural health monitoring. Ultrasonic measurements evaluated with the sensitive Coda Wave Interferometry (CWI) have the potential to detect cracks early—long before they become visible. This paper presents

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, EarlyView.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while

Toward transparent AI: Predicting strength of fly ash foam composite concrete using explainable ML models

Structural Concrete, EarlyView.
Abstract Fly ash foam composite concrete (FFC) is a sustainable, lightweight alternative to traditional concrete. However, accurately predicting its compressive strength (CS) through conventional laboratory methods is challenging due to its non‐linear behavior induced by the addition of foam content and fly ash. Also, the laboratory determination of CS

Performance of two‐to‐one non‐contact post‐installed lap splices

Structural Concrete, EarlyView.
Abstract Post‐installed lap splices ensure the continuity of steel reinforcement in concrete‐to‐concrete connections by overlapping cast‐in (CI) reinforcing bars (rebars) with post‐installed (PI) rebars. Typically, the design of such splices follows provisions originally intended for CI lap splices, despite the differences in execution and bond ...

On the behavior of flat slabs with asymmetric openings near columns: A hypothesis based on numerical simulations and design code‐based analytical models

Structural Concrete, EarlyView.
Abstract Several design codes prescribe punching shear verification in flat slabs, especially for common scenarios such as concentric punching and punching under bending moments. Although openings are generally addressed in design codes, asymmetric openings are often neglected.

Influence of steel reinforced grout configuration, and reinforcement ratio on the flexural performance of strengthened continuous RC beams

Structural Concrete, EarlyView.
Abstract The field of reinforced concrete (RC) strengthening continues to evolve as the construction industry seeks cost‐effective and sustainable alternatives to structural replacement. This study, therefore, aimed to comprehensively investigate the pioneering application of steel‐reinforced grout (SRG) for strengthening large‐scale, 3.5‐meter‐long ...
