Numerical investigations are conducted for various parameters, including uniform temperature rises, edge loading conditions, support configurations, hole size ratios, load ratios, and geometric proportions.

The study shows CCCC and SFSF boundary conditions yield the highest and lowest buckling loads, respectively. Critical buckling load decreases with temperature rise. Plates without cut-outs outperform those with cut-outs, and shorter plates under negative temperature rise achieve maximum buckling load. Uniform loading results in the lowest buckling capacity due to its larger loading area.</p></div>","PeriodicalId":596,"journal":{"name":"International Journal of Steel Structures","volume":"25 2","pages":"376 - 388"},"PeriodicalIF":1.1,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current paper presents a fault identification technique for differently tapered beams that are elastically restrained and having a tip mass. For this purpose, a method is proposed for identifying the modal parameters of an intact beam by applying continuity and boundary conditions. Then, an equivalent bending rigidity for a beam with a crack is introduced and a characteristic equation is established to estimate the natural frequency change caused by the damage. An experimental study is conducted to verify the presented method. A baseline model is updated for the intact beam before detecting the crack by updating the rotational and translational spring constants. Crack identification is then carried out experimentally based on the neural network technique. The training patterns for the network are composed of the natural frequencies calculated from the derived characteristic equation for cracked beams, along with their corresponding crack sizes and locations. The cracks are identified using the trained neural network, and those are found to be reasonably well identified. The practicality and usability of the presented technique for health monitoring of the differently tapered cantilever-type structures elastically restrained having a tip mass could be thus verified.</p></div>","PeriodicalId":596,"journal":{"name":"International Journal of Steel Structures","volume":"25 2","pages":"364 - 375"},"PeriodicalIF":1.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bracing layout state is classified according to the structure’s eccentricity, while the internal force of the bracing is adjusted according to the importance of the bracing and the symmetry of the structure, and the bracing units with a small contribution to the structure are gradually removed. Subsequently, an optimization program is employed to minimize structural weight considering multiple loading cases and constraints. The automatic optimization program was successfully applied to optimizing bracing layouts for two different steel frame structures.

Three distinct types of metal plates, namely 0.5 mm Q355 steel plates, 1 mm Q355 steel plates, and 0.5 mm 6063 aluminum plates, were utilized for pseudo-static monotonic loading tests and pseudo-static cyclic loading tests. The study delved into the impact of varying metal plate thicknesses and materials on the shear failure mechanism of the wall. The findings revealed that the horizontal bearing capacity of the double-sided metal plate shear wall hinges on the torsional deformation of the steel plate, frame deformation, and polyurethane deformation. Under cyclic loading, the steel plate undergoes deformation, recovery, and reverse deformation. Through analysis of hysteresis curves and skeleton curves, it was evident that augmenting the thickness of the steel plate enhances its shear resistance, whereas the shear resistance of aluminum plates remains relatively unchanged. Monotonic load–displacement curve analysis indicated that the initial shear stiffness increases with the increase in steel plate thickness but decreases with the increase in aluminum plate thickness.
