Special Issue Information

Dear Colleagues,

We are delighted to announce a Special Issue on the topic of "Behavior of Reinforced Concrete Structures under Extreme Conditions". The response of concrete structures to extreme environmental factors, such as fire, earthquakes, and corrosive environments, is of paramount importance in ensuring the safety, durability, and resilience of infrastructure. This Special Issue aims to bring together the latest advancements in understanding and mitigating the effects of extreme environmental conditions on concrete behaviour. Concrete structures face significant challenges when exposed to fire incidents. The high temperatures experienced during fires can cause thermal degradation, spalling, leading to the development of internal cracks and reduced structural integrity. Earthquakes pose another critical threat to concrete structures, subjecting them to dynamic loads and vibrations. Furthermore, the effects of corrosive environments on concrete cannot be overlooked. Aggressive chemicals and corrosive agents, such as chlorides, sulphates, and acids, can penetrate concrete structures, leading to degradation and weakening over time. Manuscripts addressing innovative strategies to enhance the performance of concrete in such catastrophic conditions are highly encouraged.

We invite manuscripts that delve into experimental investigations, numerical modelling, and innovative techniques focused on enhancing the performance resistance of concrete and mitigating its vulnerability to extreme conditions of fire, earthquake, and corrosion.

This Special Issue provides a platform for sharing research findings, case studies, and practical solutions related to the behaviour of concrete under extreme environmental conditions. We seek contributions that address a range of topics, including but not limited to:

  • Fire resistance of concrete
  • Fire-induced spalling of concrete structures
  • Seismic performance of concrete
  • Nonlinear behaviour of concrete under seismic loads
  • Corrosion and deterioration mechanisms in concrete
  • Innovative materials for enhanced fire and corrosion resistance
  • Fire protection strategies for concrete structures
  • Retrofitting techniques for improving the seismic resilience of concrete structures
  • Durability of concrete in corrosive environments
  • Self-healing concrete for increased durability
  • Case studies on successful applications and practical solutions

The size of the population and the need for residential spaces are increasing. One possible solution is to add new floors to existing buildings. This research examines the seismic behavior of reinforced concrete frame structures that have undergone vertical extensions by adding extra floors. The primary focus is on the joints that connect these extensions to the existing structure and the appropriate modeling of these joints. However, adding floors to existing structures might be structurally challenging, especially in terms of the behavior under seismic actions. This paper presents a numerical study of a reinforced concrete frame in an old building to which new floors are subsequently added. The analysis shows that the frame does not behave as a whole with the old part of the structure, nor does it behave the same as if it were made with rigid joints compared to additional ones connected using hinge joints. It is noted that in structural analyses, the connection between an existing structure and a vertical extension is often considered rigid, yet in practice, these joints may behave differently. The change from the corner (knee) joint to the external joint has its own effect on the distribution of internal forces in the structure as a whole and in the joint in particular. Compared to demolishing and rebuilding, vertical extension is considered environmentally friendly, reducing the financial costs, environmental pollution, and waste generation. Full article
