Implementation of Thin-Walled Approximation to Evaluate Properties of Complex Steel Sections Using C++

Abstract

AbstractSteel sections have several applications in the construction industry. They are often used in the design and construction of huge industrial complexes. They also are used in transport, shipbuilding and packaging industries. Typical steel sections are used, and their properties have been recorded and are not needed to be calculated per application. They are recorded in most design software and used easily when required. This work focusses on using thin-walled approximation to calculate the section properties of complex sections which are a combination of existing section profiles. A program is written using C++ which would apply dimensions from the user and display the section properties at the end as result. The aim is to automate the process to calculate the required values and this would in turn save time. The values obtained from the program are compared with those calculated using existing formulas and the error obtained is reported.
