Thermodynamic Effect of High-Rise Reinforced Concrete Typology on Asian Cities: Effect of Socioeconomic Obsolescence Factors on Thermodynamic Complexity

Abstract

The construction of reinforced concrete (RC) apartments played a crucial role in accommodating the substantial increase in urban populations during the post-war period in Asian cities. However, the RC process in these regions exhibits limitations in terms of the building’s life cycle duration. These limitations arise due to two main factors: the inherent hybrid nature of RC and the insufficient measures for addressing inner rebar corrosion, as well as the lack of adequate control over the management of the “structural class” amid rapid economic expansion. This study examines the impact of rapid urbanization and economic growth on the construction industry, with a specific focus on the utilization of concrete buildings. Drawing on Odum’s urban energetics theory, macroeconomic data are analyzed to investigate the patterns and implications of widespread concrete construction during the late 20th century, particularly in Asian countries. The findings are then compared with earlier periods of economic expansion in other countries, aiming to provide a comprehensive understanding of the interplay between urbanization, economic growth, and the use of concrete structures. The application of Odum’s theory enhances the analytical process, offering valuable insights into the dynamics of the macro urban energy system. In this assessment, four countries are selected based on the stage of their urban economic expansion. The selection is determined using the recent changes observed in three key factors: (1) urban concentration, (2) GDP growth rate, and (3) gross fixed capital formation (GFCF) on housing volume. The assessment identifies the point in time when production, represented by the GDP growth rate, surpasses consumption, represented by GFCF on housing volume. Through this assessment, it becomes possible to make macro-scaled predictions about the urban energy system, even with limited archival data available.
