The Method of Mirror Functions in Optimal Design of Pre-stressed Spatial Structures

The paper presents a description and analysis of a certain method of mirror functions (MMF), firstly introduced by Prof. Yu. Radtsig and later developed by Prof. I. Kholopov and the others. This method was introduced to optimize the use of lattice girders in buildings and other structures roofing. Optimal design of spatial bar structures and optimal design of lattice girders are in many ways similar. The research shows that the method of mirror functions can also be used while designing pre-stressed spatial bar structures. The authors present test calculations of using MMF in optimal design of pre-stressed spatial structures.
