Abstract

The Finite Element Method (FEM) is essential for analyzing complex structures, but a knowledge gap exists regarding result differences found between transparent manual/script methods (Excel, MATLAB) and automated commercial software (SAP2000, ETABS). This comparison is vital to address the need for transparent validation practices, especially for learning and design optimization. This study's objective is to compare key FEM outputs (nodal displacements, member forces, support reactions) using a literature review with a descriptive-analytic method. Main findings show two patterns: high consistency (results reported as "same" or <5% difference) for axial-dominated truss structures, attributed to decimal rounding ; however, large discrepancies were found specifically in bending moment components for portal frames. A data contradiction (10.89% displacement error vs. <0.1% force error) also highlighted manual implementation risks. It is concluded that FEM results are generally reliable. The practical implication is recommending transparent manual methods for learning purposes and algorithm validation , while commercial software is suited for complex professional design due to high computational efficiency.

Abstract

The rapid advancement of technology has significantly influenced structural engineering, particularly in the design of complex geometries and the analysis of irregular load distributions. Conventional manual calculations often fail to provide precise and reliable results, especially when dealing with large-scale or intricate structural systems. To address these limitations, numerical methods such as the Finite Element Method (FEM) have been developed and widely implemented. FEM divides a structure into smaller elements interconnected through nodal points, enabling detailed analysis of displacements, stresses, and reactions. Alongside theoretical development, FEM has been integrated into computer-based applications that provide more efficient, accurate, and user-friendly tools for structural analysis and design. This paper reviews several widely used FEM-based applications, including SAP2000, ETABS, ANSYS, and ABAQUS. This article utilizes the Literature Review method to review and synthesize findings from four previous studies. Each software offers unique strengths: SAP2000 and ETABS are widely applied in building and general infrastructure design; ANSYS and ABAQUS are well-suited for nonlinear and advanced multiphysics analysis. By comparing these applications, this review confirms the key finding that software specialization (SAP2000/ETABS for infrastructure vs. ANSYS/ABAQUS for advanced non-linear analysis) is crucial. Ultimately, FEM-based applications not only improve the accuracy and efficiency of structural analysis but also enhance safety, reliability, and sustainability in modern construction practices.

Abstract

The implementation of the arc-length method to enhance early-crack sensitivity in finite element models of reinforced concrete. Indonesia’s seismic vulnerability raises the importance of early crack detection for structural safety, particularly as cracks in reinforced concrete beams critically affect performance and integrity. The review compares three numerical modelling approaches—embedded reinforcement, Material Point Method (MPM), and Cracking Element Method (CEM) and analyzes their limitations in accurately capturing the onset of cracking. The embedded method often lacks sensitivity for early crack detection due to solver convergence challenges, MPM struggles with local stress concentration accuracy, and CEM depends heavily on precise crack initiation criteria. Integrating the arc-length method with these approaches significantly improves model stability and crack initiation sensitivity by enabling robust solution tracking through nonlinear and critical response phases. Case studies and referenced research demonstrate that arc-length-augmented approaches yield more reliable simulations, closely aligning with experimental results. This review concludes that the arc-length method provides a key numerical advance for early crack analysis in reinforced concrete, supporting safer earthquake-resistant design and maintenance strategies.

Abstract

The comparative accuracy of different structural models under Finite Element Method (FEM) computation remains a relevant issue, particularly when manual, spreadsheet-based formulations are compared with professional engineering software. This article integrates the findings of both studies as a basis for comparative analysis, namely (1) 3D portal analysis using MS Excel-based FEM validated with SAP2000, and (2) 3D truss analysis using a similar approach. This study aims to assess the consistency of manual analysis results based on Excel with the numerical results of modern software, as well as to understand the advantages and limitations of the method in the context of different structures. The results of the study show that in 3D portals, the displacement difference is relatively small (<5\%), but the internal moment force shows a significant difference. Conversely, in 3D truss structures, axial forces and support reactions were almost identical to SAP2000, while displacement had a considerable deviation (±10\%). This confirms that Excel-based MEH is effective as a simple educational and verification tool, but in professional practice, analysis software is still needed to ensure accuracy, especially for internal force analysis in 3D portals.

Abstract

Finite Element Method (FEM) serves as a critical numerical tool for analyzing complex composite and steel structures. This article aims to evaluate the versatility and accuracy of FEM in predicting structural behavior across diverse applications. The study reviews three specific cases: reinforced concrete encased steel columns, haunched gusset plate connections in cold-formed steel, and a mixed element method for progressive collapse analysis. Numerical simulations were validated against experimental data to assess damage mechanisms, ductility, and energy dissipation. The results demonstrate a 42% improvement in lateral capacity for composite structures and a prediction deviation of 25-29% in cold-formed steel connections. Furthermore, the mixed element method exhibited high precision with less than 2% deviation in dynamic analyses. These findings confirm FEM's reliability in optimizing structural design and developing adaptive methods for failure prediction.
