However, the existing models often fail to accurately identify the interference noise existing in the form of short-frequency and small-fluctuations, resulting in the masking of the true deformation features. Meanwhile, existing studies often focus on one-stage prediction models, discarding the rich and valuable information contained in the residual sequence. Furthermore, the existing dual-stage models often fail to deeply consider the chaotic characteristics existing in the residuals. Therefore, this paper proposes a dual-stage combined displacement prediction model for concrete dam identifying the displacement sequence interference noise and considering the chaotic characteristics of the residual sequence. Firstly, the adaptive noise complete empirical mode decomposition, the improved sparrow search algorithm and the threshold evaluation index are combined to adaptively achieve the optimal decomposition noise reduction and retain the effective deformation features. Secondly, a gradient boosting tree is utilized to fit the effective component and combine it with the processed noise component to build a high-quality residual sequence that is rich in information. Thirdly, the residual sequence is decomposed into intrinsic mode functions with different temporal characteristics by utilizing the optimized variational mode decomposition. Finally, construct a chaotic time series based on chaos theory. Taking the sample entropy as the basis of judgement, for high-frequency components, the gradient boosting tree algorithm is utilized to capture their dynamic features. For low-frequency components, the depth-separable convolutional neural network, multi-head attention mechanism and bidirectional long short-term memory neural network are organically combined to comprehensively learn the deformation features. Case analysis shows that the RMSE of the model proposed in this paper in the measurement point PL11–5 sequence has reached an astonishing 0.0794, and the maximum improvement degree compared with the control model has reached 79.35 %. The results show that this model obtains strong generalization ability and high robustness, and can provide reference for dam safety monitoring.</div></div>","PeriodicalId":50866,"journal":{"name":"Advances in Engineering Software","volume":"211 ","pages":"Article 104045"},"PeriodicalIF":5.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321137","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}

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.

A parallel optimization framework for structural topology and building direction is proposed by extending the classical compliance minimization formulation. And, to be applicable to gradient-based optimization algorithms, sensitivities related to density and angle variables are derived separately.

The proposed system integrates geographic information system (GIS), BIM, and structural analysis tools. To this end, the study first introduces the overall framework and the seismic performance assessment methodology. The framework is developed to support the generation, analysis, and updating of network-level BIM. To generate the BIM for a road facility network, an algorithm is developed that automatically generates terrain surfaces and road facility objects by linking GIS data. 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.

Ensuring seismic resilience of such sites has become critical for nuclear safety. Near coasts or rivers, groundwater table (GWT) fluctuations significantly influence soil-pore water distribution, thereby affecting soil seismic response and NPP performance. 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.

Fast-computing beam-element models are insufficient to accurately capture local stress concentrations at the intersection region, leading to inaccurate lifetime predictions. In this work, a high-fidelity numerical modeling tool, HFJOINT, is developed for stress concentration analysis of welded tubular joints, following a user-friendly process. The workflow begins with the creation of an elementary T/Y-joint using quadratic hexahedron elements, where the weld geometry is generated in accordance with the American Welding Society (AWS) standard. The chord and brace are divided into several regions allowing for an entirely structured mesh. The geometric transformations of multiple elementary joints enable creating more complex joints. After evaluating the stiffness matrix, the beam-element forces are converted to external tractions, and are transformed into solid-element nodal forces via Gaussian integral. The boundary conditions are defined from the geometric constraints formulated by the Lagrange’s equation of the second kind. Based on the nodal displacements, the postprocessing module evaluates the local stress at any point. Using linear extrapolation, the hot-spot structural stress and the stress concentration factors (SCFs) along the weld circumference are computed.
