Steel Structure Inspection Using a Laser Scanner Device with Finite Element Method

Abstract

The following research covers optimal solutions for design of connection joints in metal structures based on digital modeling and 3d scanning devices. The paper discusses the properties of metal as a building material, welds and bolted joints, where to use the FEM finite element method in practical application, as well as the stages of CAD computer modeling. Computer aided design covers the development of geometric shapes in a digital format. The structural model is designed using a portable laser scanning device. One of the joints is selected and a unit of force as a load is applied. The finite element method is the most common tool for solving engineering problems. Problems may concern structural loads, temperature transfer, fluid flow or electromagnetic potential. To solve given issues, finite element analysis involves transforming a large complex system into smaller elements. While it is easier to solve a small element using given variables, it can be solved for a large system.
