Challenges on contemporary architectural technology on durability of reinforced concrete structures

Abstract

PurposeThis study aims to discuss the causes of short-lived structuring of contemporary buildings. The life expectancy of structures may be theoretically predefined during the state of the design. This time period, known as the service life of structures, is determined by the load or the deformation level at which irreversible failures of the bearing structure may occur. On the other hand, planned obsolescence and perceived obsolescence, observed in the western world since the first half of 20th century, are currently setting an economic reality and are part of an expanded framework that, apart from architectural structures, extends to all design fields. The effects of short-lived structuring on environmental and energy terms are presented and theoretical and experimental recommendations from the literature are cited, as well as recommendations that have already been successfully applied in some countries.Design/methodology/approachThis study aims to discuss the issues associated with short-lived structuring, durability and obsolescence of contemporary structures. For this purpose, theoretical and experimental recommendations from the literature are cited, via an extensive state of the art research.FindingsShort-lived structuring has been a field of research during recent years. Terms such as durability are being introduced into Design Codes, while trends like perceived obsolescence and environmental impact raise issues for research. Moreover, the results of short-lived structuring are becoming more and more apparent, indicating an unsustainable reality. Issues like maintenance of structures, sustainability in design, corrosion effects, repair techniques and building waste management are an important field of research among the engineering community. In this study, the parameters affecting the lifespan of contemporary structures have been discussed.Originality/valueThe effects of short-lived structuring on environmental and energy terms are presented and theoretical and experimental recommendations from the literature are cited. The parameters studied herein concern material properties and design approach but also environmental and energy-related ones.
