Sažetak
Optimization of the dimensioning of structural structures is gaining momentum. FEM, evolutionary, and other methods are found that are transformed by algorithms into computer simulations of construction models. Using existing methods and interconnecting and merging these structures yields a new, seemingly complicated, but simple method that computers can easily support with software loops. By setting the geometric characteristics of constructive lattice systems in equation lines, formulas are obtained that replace even trigonometric equations. The Ritter-Križaić iterative method for one-sided gratings with a flat lower band is also defined. This method paves the way for new methods to define different types of grids. By solving demanding models, i.e., by defining an iterative model with oblique rod belts sticks, the definition of spatial variables necessary for static dimensioning of structures is accelerated. As a result, the approach of simple n-polygonal structural modeling of truss continuous construction with combination direction coefficients and defining differential equations of a grid's continuum in displacement with the Mathcad toolset is developed.
