Economic effectiveness of traditional building materials in modern conditions

Abstract

The article studies the effectiveness of different materials usage in building structures. Specific researches and estimates have been done to complete this study. Economic usage indicators of materials with different properties for creation of identical building structures were compared. Impact of the following material properties such as strength, elastic modulus, weight and cost on the construction cost was estimated. Rafter construction was selected as a study object. Calculations examples of rafter constructions made of wood and steel are described in the paper. Material properties impact on operational characteristics of the building structures was estimated. Variant design and optimal design of constructions made of materials that properties considerably differ were reviewed. Variant design example used in the building practice was described.
