Athlone Institute of Technology parchbold@ait.ie Abstract

Interactive, reusable learning objects are being developed to aid the teaching of structural engineering modules within the Department of Civil, Construction & Mineral Engineering. Further, laboratory practicals are an established means of teaching and are commonly used throughout the existing programme delivery modes, while the use of finite element models to simulate loading and structural responses is studied in higher level programmes. This paper describes the development, calibration and verification of FE models, which can be used to simulate the loading and response in two laboratory practicals currently undertaken by undergraduate students. These simulations will be incorporated into reusable learning objects to aid the teaching of the relevant engineering principles and to better prepare students for the actual laboratory practical sessions.

Introduction

As part of the teaching and learning strategy for modules in civil engineering programmes in AIT, innovative and interactive methods of teaching are being developed to promote student engagement and to cater for a broader range of learning styles, while also facilitating greater accessibility to class content. Currently students undertake laboratory practicals to further understand theory in the area of structural engineering. In order to further integrate the learning from the laboratory practicals into the theoretical classes and vice-versa, finite element models of two common laboratory structures were developed. This facilitates the study of the mechanical behavior of these structures to validate assumptions made in class in relation to material behavior. Further, they can be used to better prepare the students for carrying out the practical work once they enter the laboratory. In order for these finite element models to have validity, they were calibrated and verified through comparison with actual experimental data recorded in the laboratory. It is envisaged that these numerical simulations will also form the basis of reusable learning objects currently being developed for use in teaching aspects of structural engineering. This paper describes the development, calibration and verification of these finite element models.
