The grey wolf optimizer (GWO) is a widely adopted classical algorithm in this field, with IGWO representing a prominent improved version. To overcome the shortcomings of IGWO in global exploration, the imbalance between exploitation and exploration, and the static nature of neighbor selection in the DLH strategy, this paper introduces a novel metaheuristic algorithm called MYIGWO. The algorithm integrates a dual mutation strategy, adaptively selecting mutated individuals via differential random perturbations. By ranking individuals according to fitness, Cauchy mutation is applied to some lower performing individuals to strengthen global exploration, while the remaining selected individuals are subjected to polynomial mutation to enhance convergence speed and the ability to avoid local optima. Additionally, a directional correction is introduced to the mutated individuals to stabilize the mutation outcomes. Lastly, the DLH strategy’s neighbor radius is dynamically adjusted using chaotic mapping, enabling flexible neighbor selection. The optimization performance of MYIGWO was systematically evaluated using multiple performance metrics, and MYIGWO was compared with eighteen advanced meta-heuristic algorithms on multiple benchmark test sets. Moreover, MYIGWO was applied to four classical engineering optimization problems and robot path planning task. The results show that MYIGWO exhibits significant performance advantages in all experiments. In particular, it showed significant improvements in the global optimal solution search capability over the original algorithm.

The novelty of this work lies in integrating multi-objective optimization of PFTMDs with consideration of SSI effects, providing a comprehensive comparison with active damping strategies under various soil conditions. A multi-objective marine predator algorithm (MOMPA) is employed to optimize the damper parameters. The analysis incorporates four earthquake ground motion records and three soil types: soft, medium, and dense. The optimized performance of the PFTMD is compared to that of an active friction-tuned mass damper (AFTMD), which is controlled by a proportional-integral-derivative with filter (PIDF) controller, also optimized via MOMPA. Both control strategies are benchmarked against an uncontrolled structure. The results indicate that both systems significantly enhance the seismic performance of the structure by reducing displacement, acceleration, and inter-storey drift. However, the AFTMD consistently outperforms the PFTMD across all soil conditions. To account for the unpredictability of seismic events, the study further assesses damper performance using averaged parameters derived from multiple earthquake-soil combinations. While the PFTMD performs effectively when tuned for specific conditions, its performance declines under averaged settings and can even amplify structural responses. Conversely, the AFTMD shows robust and consistent performance, establishing it as a more reliable solution for seismic mitigation in tall buildings.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"211 ","pages":"Article 104036"},"PeriodicalIF":5.7,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158800","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}

However, the complex geometrical properties of the structure lead to huge simulation complexity for high-precision dynamics simulation, and the existing equivalent parameter acquisition methods are difficult to accurately characterize the dynamics behavior of the actual structure, which greatly limits the application of TPMS structures in engineering. To break through the limitation, the present paper investigates the dynamic response behavior of Gyroid lattice sandwich plates under moving load. Based on the three-dimensional elasticity theory, the dynamic numerical model of Gyroid lattice sandwich plates under moving load is established by combining the spectral geometry method (SGM) and artificial virtual spring method. By employing the parameter inversion technique based on the dynamic properties, the equivalent material parameters of Gyroid lattice in terms of dynamics are introduced to directly identify, which effectively avoids the distortion of dynamic properties and the boundary non-periodic error that may be caused by the traditional static equivalent parameters. Finally, the effects of the lattice parameters and the type of moving load on the dynamic characteristics of the structure are systematically analyzed. Especially, the influence of lattice thickness ratio on the dynamic characteristics of the structure can provide an effective reference value for engineering design, thus realizing a wider application prospect of TPMS lattice sandwich plates in engineering.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"211 ","pages":"Article 104038"},"PeriodicalIF":5.7,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096629","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}

While conventional aluminum honeycomb devices achieve high specific energy absorption, they suffer from complex fabrication, require full replacement after minor impacts, and generate high rebound velocities that can exacerbate secondary damage. In this study, we propose a Multi-layered Nested Tubular Structure (MNTS)—an arrangement of adjustable square and circular thin-walled tubes—as an alternative absorber. A physics–based finite‐element (FE) model, incorporating material nonlinearity, simulates a lead‐car collision against a rigid wall and is validated against full-scale experiments (velocity: 8.357 m/s; mass: 54 t). The model accurately reproduces peak absorbed energy, average force response, displacement history, and rebound velocity. A parametric study of 144 FE simulations combined with response surface methodology identifies optimal wall‐thickness parameters (<em>λ_s</em> = 7.4 mm, <em>λ_c</em> = 18.6 mm), yielding a maximum energy absorption of 1.728 MJ (<em>R_MSE</em> = 0.0477 MJ, <em>R</em>² = 0.945). Building on these results, we develop a reduced‐order analytical model using logistic regression to relate train speed (5.0–9.0 m/s) to peak force, maximum displacement, and energy absorption, achieving an <em>R</em>² of 0.989 for displacement predictions. Validation against 41 additional FE runs confirms the analytical model’s accuracy while reducing computational cost by orders of magnitude.

In addition, a method for extracting and transforming object information from the BIM is established to enable BIM-based numerical modeling and integration with analysis tools. Seismic performance is evaluated by separating structural and functional performance at both the individual and network levels. To demonstrate the feasibility and applicability of the proposed framework, we applied the proposed framework to Gyeongju, an area damaged by seismic events in South Korea, to generate the network BIM and perform seismic simulations.

To analyze the influence of groundwater table on the seismic response of the nuclear power plant, this paper uses the saturated porous medium model and considers the interaction of the saturated soil and structure. The free field of the horizontally layered site of dry soil-saturated soil is obtained by the transfer matrix method, and combined with the transmission boundary, the wave input of soil-structure interaction (SSI) analysis is realized. Then, the partitioned parallel calculation method of SSI is used to analyse the saturated SSI. The soil, along with its groundwater, is characterized using the generalized saturated porous medium model. The simulation of the combined lumped-mass explicit finite element and transmission boundary is accomplished through a self-programmed FORTRAN code. On the other hand, the structural analysis is carried out using ANSYS, employing an implicit finite element approach. Taking a nuclear power plant as an example, the dynamic response of the soil-foundation-nuclear power plant system is analysed at five sites with different GWTs.
