Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 12, Page 1886-1908, 15 June 2024.Abstract As urban population increases, integrated underground–aboveground complexes are being constructed at growing paces in major cities. The seismic analysis of such complexes is crucial for the safety and functionality in the threat of potential earthquake disasters.

On the stability of mixed polygonal finite element formulations in nonlinear analysis
International Journal for Numerical Methods in Engineering, Volume 125, Issue 9, 15 May 2024.Abstract This article discusses the accuracy and stability of the pressure field in nonlinear mixed displacement‐pressure finite element formulations in solid mechanics. We focus on two‐dimensional mixed polygonal finite element formulations with linear displacement and constant pressure approximations in particular.

Civil Engineering Design, Volume 5, Issue 5-6, Page 67-94, January 2024.Abstract In civil engineering, carbon is typically regarded as a modern material to serve as reinforcement in concrete structures. Compared to steel reinforcement, it features two substantial benefits: It is not sensitive to corrosion, and has an enormously increased tensile strength.

Scaled boundary finite element method for fluid-structure interaction [PDF]
, 2006 This study presents the first attempt to extend the scaled boundary finite element method (SBFEM) for Fluid-Structure-Interaction problems. A fluid velocity-to-pressure relationship based on the SBFEM and acoustic approximations is developed. A FEM/SBFEM

Comparative Study of Algorithms for the Conversion From Surface Mesh Models to Volume Mesh Models
Advances in Civil Engineering, Volume 2024, Issue 1, 2024.The study delves into the performance of different algorithms in the process of converting surface mesh models (SMMs) into volume mesh models (VMMs) required for finite element analysis. The experiment compared the Initial mesh, Delaunay, Frontal, and HXT algorithms, analyzing their central processing unit (CPU) runtime, node count, element count, and ...

Scaled boundary FEM solution of 2D steady incompressible viscous flows [PDF]
, 2008 In this paper, the scaled boundary finite-element method (SBFEM) proposed for wave-structure interaction [Tao et al, 2007] is extended to solve two-dimensional (2D) steady incompressible viscous flows governed by the Navier-Stokes (N-S) equations.
