Behavior of High Rise R.C. Buildings Under the Effect of Thermal Stresses
Authors
Abstract
The global phenomenon of climate change has emerged as a critical driver of long-term environmental alterations, imposing unprecedented challenges on various sectors. Among these challenges, the impact of temperature variations on structural integrity remains an under-addressed concern, particularly in the context of high-rise buildings. This paper sheds light on the imperative need for an integrated approach to structural design that accounts for climate-induced thermal stresses alongside seismic and wind load considerations. This study addresses this gap by proposing a comprehensive framework for incorporating climate-induced thermal stresses into the structural design process, specifically tailored to Egypt's evolving weather patterns. The Egyptian design code provides minimal guidance on temperature effects, primarily focusing on the consideration of thermal stresses when structural lengths exceed predefined limits. However, this provision fails to capture the magnitude of temperature fluctuations anticipated due to climate change. To assess the vulnerability of high-rise buildings to temperature-induced stresses, a thorough analysis is conducted on various structural systems commonly employed in Egypt. The investigation covers prevalent seismic, and wind loads as well. By simulating the effects of current and projected temperature changes, the study evaluates the potential risks posed by thermal stresses on the structural integrity of high-rise buildings. The findings underscore the need to revisit existing design equations and safety factors, recalibrating them to account for the evolving climate scenario.
