Optimization of bearing capital of structural roof slab

Abstract

The problem of exploring the optimum alternative of bearing capital of structural roof slab design solution is set and worked out in the article. As a method of searching for the optimum alternative, the parametric optimization method is used. Previously, a number of examples illustrate the application of this method. Then one variable parameter is chosen so that its changing provides a graph of objective function behavior, which in turn provides an optimal constructive solution according to the assumed optimality criterion. Constraints of the problem are strength and sustainability regulatory requirements and also a number of design parameters. Metal consumption was assumed as an optimality criterion. The work presents efficiency and relevance of optimization procedures while searching for design solutions at the early (conceptual) stage of design, which provide for an engineer the necessary information to choose reasonable design solutions based on options analysis.
