Special Issue Information

Dear Colleagues,

The numerical simulation of structures has developed considerably over the last few years. The techniques and approaches used to simulate small up to large-scale structures are being updated and improved to support the engineers and their decision-making in design, rehabilitation, and maintenance. The evolution of numerical simulation has allowed the engineering industry to reach complex projects and raise the bar for the development of efficient, sustainable, and safe structures. Additionally, recent algorithms are supporting the reduction of computational time and effort, which may play a critical role in the industrial environment of nowadays.

This Special Issue aims to cover the recent advances and challenges in the numerical simulation of civil engineering structures. We invite the submission of new research, case studies, projects, reviews and state-of-the-art discussions related to the numerical simulation of structures. In addition, the works can be related to the following topics:

  • Engineering optimization
  • CAD Integration
  • Multiscale and multiphysics applications
  • Crash and impact simulation
  • Strengthening and retrofitting
  • Approximation techniques (FEM, FV, DEM, BEM, PUM and meshless methods, isogeometric analysis, phase-field modeling)
  • Domain decomposition methods
  • High order methods
  • Coupling strategies (Fluid-structure interaction, multi-model, multiscale)
  • Optimal control
  • Error estimation and mesh/modeling adaptation
  • Stochastic approaches, Uncertainty quantification
  • Algorithms
  • Parallel computing
  • Code development
  • High Performance Computing
  • Image processing
  • Mesh generation
  • Machine learning and data-driven approaches

Stability calculation is the main objective during the analysis of domes. To investigate the effects of the initial defect, geometric nonlinearity, and material nonlinearity on the stability performance of different dome structures, 60 m numerical models were built and optimized by an iterative force-finding APDL program. Then, linear buckling analysis, geometric nonlinear stability analysis, geometric nonlinear stability analysis with initial defects, and dual nonlinear analysis with initial defects were discussed to compare the stability performance of ridge-beam cable domes (RCDs), suspen-domes, and conventional cable domes via finite element analysis. The results show that the buckling loads all follow the order of initial defect + dual nonlinear analysis < initial defect + geometric nonlinear analysis < geometric nonlinear analysis < linear buckling. The addition of ridge beams improves the overall stability and transforms the instability modes from local concave instability to overall torsional buckling. The ultimate load amplification coefficients of the RCD are close to those of the suspen-dome, while the vertical displacements of the RCD are more than those of the conventional cable dome, so the RCD has sufficient stiffness to reduce local displacement. Under 2–3 load combinations, internal ridge beams change from a tensile-bending state to a compressive-bending state, causing the entire instability of the RCD afterwards. Full article
