Abstract

In the described research, simulation models for analyzing a variety of structural problems were developed utilizing the Abaqus FEA software package. The produced “cae” files and AVI animation files produced in the study are planned to be used to better clarify some of the more important structural engineering topics and further enhance an introductory Structural Analysis course in the Civil Engineering and Construction Department at XXX University. The specific tasks associated with the conduced investigation were assigned in the second phase of a research project assigned to an honors student in the fall of 2021. To better establish the significance of the project, sample produced simulation models for some of the studied structures are provided and discussed in the paper. These include models of frames with multiple connected parts, various truss types, and several two-dimensional multistory building frames subjected to different loading conditions. The developed simulations can provide the distribution of the internal shear, axial load, and bending moment along the length of each studied structural part, as well as yield the corresponding deformation and stress results. By interacting with the produced models during the lectures, the instructor can effectively enhance the students’ understanding of the behavior of structures subject to various loads and further promote student learning. The results obtained from the simulations were all almost identical to the theoretical values, except in cases where approximate methods of analysis were used. These methods include the classical Cantilever Method and Portal Method of analysis for analyzing building frames subjected to lateral loads, as well as another approximate procedure used for analyzing these frame types subjected to vertical loads. In these specific cases, the finite element results obtained using Abaqus yielded more accurate results. Expertise gained and techniques developed through undertaking this project serve as an invaluable tool to foster other more in-depth investigations for analyzing a variety of other more complicated structures.
