The development of chart based method for steel beam designs using the Russian sections

Introduction and objectives. Russian steel construction does not cover the chart method for steel beam design and experimental works need to be implemented to investigate the behavior of the charts However, the experimental tests are expensive, tedious and time consuming to be conducted. The objective of this paper is to compare and validate the accuracy and reliability of the chart method for steel beam design by correlating moment capacity and bracing length (Φ M n, L b) curves between different sections and this strategy is more helpful in determining the lightest steel sections without trial and error. Materials and methods. Alternatively, a strategy to use the AISC-LRFD's chart-based method, which plots the relationships between the flexural capacities of steel sections and their unbraced lengths of lateral bracing and weights, will be helpful in determining the lightest sections in terms of their lateral bracing requirements and moment capacity. In other words, the most optimum steel sections can be obtained without trial-and-error process. Results. If the design with a chart-based method using the Russian steel sections is developed, it can be used to design steel beams more quickly and economically.
