Choice of Sustainable and Durable Concrete Structure Using LCA

Abstract

The paper presents a new perspective on the issues of life cycle assessment (LCA) and durability analysis of structures. In the case study, a comparative analysis of three variants of the chosen structure was performed. Subsequently the durability of all variants was assessed. The structural solutions were modified to achieve a targeted life cycle for all variants. Modified structures were evaluated in LCA. The study points to the fact that orthodox compliance with code prescriptions can lead to an uneconomical and unsustainable solution and suggests an approach where the design of the structure is adjusted for the required service life.
