As a result of this curvature, these structures present significant complexities, both in their performance and design, when compared to equivalent straight girders. This fact explains the limitations of current design specifications, which appear to either inadequately address the design of such girders under different loading scenarios or to offer limited and simplified guidance only. AASHTO adopts a simplified and empirical approach, providing some design guidelines for curved steel plate girders. In contrast, the current and upcoming versions of Eurocode 3 for plated structures (EN 1993-1-5) lack specific provisions for curved steel plate girders, especially regarding their response to patch loading, and the adoption of the provisions for straight girders has been shown to provide rather inaccurate and overly conservative predictions. To address this issue, this paper presents a practical procedure for estimating the patch loading resistance of curved steel I-girders. The work is based on a comprehensive finite element investigation on curved steel plate I-girders subjected to patch loading. The new proposal features a novel expression for calculating the buckling coefficient that considers the effect of curvature for a more accurate prediction of the elastic critical load of curved steel I-girders, in addition to a novel resistance function specific to these structures. The new proposal is found to offer a more precise and consistent resistance prediction, by incorporating curvature effects, that the current provisions for straight girders.</div></div>","PeriodicalId":15557,"journal":{"name":"Journal of Constructional Steel Research","volume":"229 ","pages":"Article 109469"},"PeriodicalIF":4.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, the optimum HPGC mix design was combined with stainless steel tubes, providing significant advantages in harsh marine environments in resisting corrosion and chemical deterioration. Four short columns having a height of 900 mm were tested under different eccentricities to depth ratios (e/D) (0, 0.06, 0.267, and 0.467), and a beam having a length of 1200 mm was also subjected to three-point flexural bending to complete the axial-moment interaction diagram experimentally. Additionally, finite element modelling (FEM) was conducted to simulate the fabricated columns in the experimental program. The results showed an agreement between the numerical and experimental behaviour of the columns. Moreover, the interaction diagram was plotted analytically to assess the capabilities of existing models and accurately predict the results. The experimental findings revealed that the presence of the stainless-steel tubes, which encase the HPGC, improves the ductility of the columns, even though there was a reduction in axial load capacity with increasing the e/D. Local buckling failure was observed at the mid-height of all columns.

Traditional deflection calculation theories for GBCSWs assume that the CSWs fully resist shear forces, resulting in shear deflection. Meanwhile, the concrete flanges are assumed to bear the entire bending moment, contributing to bending deflections. However, this study demonstrates that these assumptions are insufficient for accurately predicting deflections in tapered configurations. In tapered GBCSWs, the Resal effect induces additional shear forces within the CSWs, resulting in additional shear deflection that significantly affects the total deflection, a phenomenon that is absent in prismatic GBCSWs. Additionally, this study represents the first comprehensive investigation of the Resal effect, revealing its dual influences—both positive and negative—on the deflection behavior of tapered GBCSWs. The positive Resal effect contributes to a decrease in the effective deflection of GBCSWs, whereas the negative Resal effect results in an increase in deflection. Failure to account for the Resal effect and the use of traditional methods for calculating deflections in tapered GBCSWs can lead to considerable inaccuracies. This research not only investigates but also clarifies the mechanisms by which the Resal effect influences the deflection behavior in tapered GBCSWs. Additionally, modified formulas for predicting the deflection of tapered GBCSWs are proposed. The accuracy of the modified method was validated through experiments and numerical simulations.</div></div>","PeriodicalId":15557,"journal":{"name":"Journal of Constructional Steel Research","volume":"229 ","pages":"Article 109525"},"PeriodicalIF":4.0,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, for the first time, identifies significant differences between the shear behaviors of prismatic and tapered BGCSWs under eccentric load.
