Abstract
This study aims at demonstrating the development and implementation of a web-based computer software, WAFEC (Web Application for Finite Element Calculations) created using JAVA, J2EE programming environment to solve finite element problems related to structural engineering by utilizing direct stiffness method approach. It is designed to perform modeling of the global stiffness matrix, and calculate deformation and forces for one-, two- and three-dimensional finite elements by overcoming limitations of existing software’s. Most of the existing finite element software’s are desktop applications and they require prior installation, basic understanding of the software before use, and are time consuming which makes it difficult to get an instant solution for the user.
Obtaining stiffness matrix using this approach, is not only difficult but also not easily comprehensible, because the results obtained are not in a proper readable format. More ever most of the software’s are commercial software’s hat are more oriented towards industrial applications rather than academic usage. The major purpose of this paper is to develop a computer software to solve problems with infinite nodes and elements in a limited amount of time and to increase the flexibility of use with the help of internet. The robust code is designed to perform analytical calculations for elements in different complex connection structures. The architecture of software created is based on MVC framework which is formed by utilizing Java Server Pages to form user interface that helps to perform data entry, Servlet to perform stiffness calculation and MySQL to store the results. Application of proposed web-based software in solving practical problems is demonstrated by carrying on several case studies utilizing different finite elements and comparing it to a few other software’s based on student feedback.
