Published: March 4, 2025

Abstract Fiber reinforced polymer (FRP) has emerged as a significant advancement in construction, with design provisions outlined by codes such GB/T 30022‐2013, CSA S806‐12 (R2017), and ACI 440:2015. While the use of FRP bars alternatives to conventional reinforcement columns been extensively studied, their application hollow concrete (HCCs) remains underexplored. This study investigates behavior FRP‐reinforced HCCs using advanced machine learning (ML) models, focusing on prediction two critical outputs: first peak load (Y1) failure (Y2), based eight input parameters. Models evaluated include extreme gradient boosting (XGB), light (LGB), categorical (CGB). A rigorous comparative analysis demonstrated that all models achieved high predictive accuracy, deviations within ±10% actual results, validating reliability. Among CGB exhibited superior generalization robustness, emerging most reliable predictor for HCC behavior. To enhance practicality, user‐friendly graphical user interface was developed allow engineers parameters instantly obtain predictions Y1 Y2. not only advances understanding but also bridges gap between computational real‐world applications, contributing robust tool structural engineering design.

Published: March 3, 2025

Abstract Piano Key Weir (PKW) is an advanced hydraulic structure that enhances water discharge efficiency and flood control through its innovative design, which allows for higher flow rates at lower upstream levels. Accurate prediction crucial PKW performance within various management systems. This study assesses the efficacy of Artificial-Neural-Network (ANN) Gene-Expression-Programming (GEP) models in improving symmetrical PKWs. A comprehensive dataset comprising 476 experimental records from previously published studies was utilized, considering a range geometric fluid parameters (PKW key widths, height, head). In training stage, ANN model demonstrated superior determination coefficient (R 2 ) 0.9997 alongside Mean Absolute Percentage Error (MAPE) 0.74%, whereas GEP yielded R 0.9971 MAPE 2.36%. subsequent testing both displayed high degree accuracy comparison to data, attaining value 0.9376. Furthermore, SHapley-Additive-exPlanations Partial-Dependence-Plot analyses were incorporated, revealing head exerted greatest influence on prediction, followed by height width. Therefore, these are recommended as reliable, robust, efficient tools forecasting Additionally, mathematical expressions associated script codes developed this made accessible, thus providing engineers researchers with means perform rapid accurate predictions.

Hydraulic assessment of different types of piano key weirs

ISH Journal of Hydraulic Engineering, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 24

Published: Oct. 17, 2024

Piano Key Weir (PKW) is a non-linear weir with small foundation footprint that allows large discharges through narrow channel. The presence of overhangs classifies it into A, B, C, and D. For different PKW types, this study aims to assess the discharge, hydraulic characteristics (flow regimes, water surface profile, nappes interference), energy dispersion. This employs FLOW-3D software validated by comparing experimental types A D numerical simulations. Experimental simulation results agreed well, lower MAPE values for both types. After that, eight simulations each type were run, headwater ratios (Ht/P) from 0.13 0.85 (Ht: total upstream head above crest, P: height). Regarding discharge performance, type-B was superior all other at heads (Ht/P ≤0.40) due longer overhangs. While higher > 0.40), type-A became highest type. Since PKWs disperse more effectively than linear weirs, they acquire new performance as dissipators. Type-C had dispersion rate, followed type-A, type-D, type-B. Finally, an empirical equation provided predict rates over function coefficient.
