Technological parameter optimization of multilayer enclosure structures with the multiple-criteria decision analysis

Abstract

Nowadays modern monolithic construction is moving toward in balanced structural safety improving, energy efficiency and cost reduction with no-loss in quality characteristics. All this trends are possible due to bearing and enclosure wall construction technology optimization. Construction process efficiency is closely bounded with innovative material using both with a selection of effective work technology. To determine and justify the choice of material and construction technology researches are conducted. To select the most effective combination in the construction of enclosing building design, a multiple-criteria decision analysis of the work processability is used. The conducted numerical researches and the analysis of results have revealed that the most effective solution from the point of view of construction manufacturability of building enclosing structures and also which corresponds to the requirement of building heat protection is the using of monolith sandwich – multi-layered monolithic structure with a low-thermal conductivity concrete as a monolithic thermal insulation layer.
