Study of the number of different types of truss elements

Objective. The purpose of this study is to develop an algorithm for determining the optimal number of different types of elements that will minimize the cost of structures. The article presents specific calculations for optimizing the number of different types of truss elements for spans of 24 meters, 30 meters, and 36 meters. Method . The study is based on the application of numerical and analytical methods for calculating steel consumption depending on the number of different types of truss elements. Result . The considered design and calculation schemes allow us to determine the optimal number of different types of truss elements that minimizes the cost of the rod system (truss). The results are presented in the form of graphs and tables. Conclusion . The results of this study allow us to determine the optimal number of different types of elements even at the design stage of trusses with different spans.
