Web application for size and topology optimization of trusses and gusset plates

Abstract

With its ever growing popularity, providing Internet based applications tuned towards practical applications is on the rise. Advantages such as no external plugins and additional software, ease of use, updating and maintenance have increased the popularity of web applications. In this work, a web-based application has been developed which can perform size optimization of truss structure as a whole as well as topology optimization of individual gusset plate of each joint based on specified joint displacements and load conditions. This application is developed using cutting-edge web technologies such as Three.js and HTML5. The client side boasts of an intuitive interface which in addition to its modeling capabilities also recommends configurations based on user input, provides analysis options and finally displays the results. The server side, using a combination of Scilab and DAKOTA, computes solution and also provides the user with comparisons of the optimal design with that conforming to Indian Standard (IS 800-2007). It is a freely available one-stop web-based application to perform optimal and/or code based design of trusses.

The Influence of Mesh Density on the Results Obtained by Finite Element Analysis of Complex Bodies

“…For a cantilever beam, Krishnamoorthi et al [ 8 ] present yield values, using finite element analysis with different fineness of discretization, compared to the exact value determined analytically. The convergence of the numerical solution to the exact value of the analytical solution is highlighted, the difference being small when the numerical solution considers more than 1200 elements.…”
