A total of five double-half-span subassemblies were tested under a middle-column-removal scenario, involving various pallet loads, beam spans, connection types and bolt numbers. Three main failure modes, including tab cracking, bolt bearing and beam end failure and their combination, were observed in the tests. The development of the collapse-resisting mechanisms in the subassemblies are analyzed. Both flexural action and catenary action contribute to the collapse resistance of the subassemblies, with catenary action dominating ultimate resistance. The effects of critical geometric parameters on the collapse-resisting performance are also investigated. The ductility of the subassembly is improved when the beam span increases and the pallet loads exist. For Tab + Bolt (TB) connections, increased bolt number leads to increase of ultimate resistance and to decrease of ductility. For purely-bolted (PB) connections, increased bolt number impairs both ultimate resistance and ductility. Therefore, compared with the PB connections, the TB connections are preferable due to their better ductility in the collapse-resisting design. Moreover, a theoretical model based on the Component Method is developed to characterize the full-range load-displacement behaviour of beam-to-upright subassemblies.

Enhancing energy absorption through combined methods while maintaining response stability and cost-effective remains challenging. In the study, compact ring-shear structures with superior properties are combined; the energy absorption mechanism of combined structures with multiple compact ring-shear units (CRS) is explored. Impact tests and simulations reveal that increasing the number of identical units in a CRS induces a saturation effect, reducing the stability of energy absorption. A misalignment strategy is proposed to improve performances of the CRS by evenly distributing the peaks of impact force-displacement curves among units. This method significantly improves both energy absorption and response stability of the CRS. The optimal number of units is determined based on the ratio of overlap thickness to ring thickness, with a recommended ratio of approximately 0.5. The impact response of the CRS under oblique impacts and various array configurations is also evaluated, demonstrating stability across different conditions. The practical applicability of the misaligned CRS in confined-space brake systems is validated through design, testing, and simulation.

The incorporation of non-uniform spline functions effectively overcomes the inherent absence of local modification in the traditional finite strip method (FSM), enabling precise modeling and local mesh refinement of cutouts for accurate predictions of buckling behaviors. The convergence and validation studies confirm the accuracy of the developed N-u SFSM for buckling analysis of structures featuring cutouts. Furthermore, by optimizing the spline interpolation points, the number of knots is reduced, and the computational efficiency is significantly improved compared to the existing spline finite strip method (SFSM). The versatility of the method is demonstrated by its effective use in both the perforated plates and cylinders, where diverse configurations of cutouts in terms of size, shape, quantity, and location are analyzed.

However, their shallow structural depth and slender members render them susceptible to buckling failures under significant moments or compression forces. One under-explored approach to addressing this issue is the strategic addition of structural members as a second layer to a base grid. This paper tackles the challenge of identifying optimal member layouts in double-layer grid structures, through a density-based topology optimisation problem. In this approach, candidate members, arranged in-plane and out-of-plane with respect to the base structures, are considered as design variables. The problem is formulated based on the Solid Isotropic Material with Penalisation (SIMP) method to minimise compliance while satisfying constraints related to material volume and structural stability. To address stability concerns, linear buckling loads derived from an eigenvalue analysis are employed as constraints. To diversify optimisation results, regions with dense material distribution are split using local material constraints at the element level. The efficacy of this methodology is tested on a double-layer elliptic paraboloid grid shell with a square on-plan projection subject to a uniformly distributed vertical load. The stability characteristics of the optimal structures are further evaluated through geometric non-linear analysis. A comparative analysis of static compliance and non-linear critical loads under various external loads reveals that structures optimised with high stability limits and local material constraints generally exhibit enhanced robustness, characterised by improved stability and stiffness. Additionally, the versatility of the method is showcased through its application to a composite hyperbolic paraboloid grid shells featuring diverse mesh configurations.</div></div>","PeriodicalId":15557,"journal":{"name":"Journal of Constructional Steel Research","volume":"227 ","pages":"Article 109323"},"PeriodicalIF":4.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143355232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
