Behavior and design of earthquake-resistant concrete structures

Earthquakes, as one of the primary natural disasters, cause significant destruction to building structures. Historically, the collapse of buildings due to earthquakes has resulted in numerous casualties and economic losses. This paper, through a method of literature review, explores the mechanisms of damage to concrete structures under the action of an earthquake and presents the principles of earthquake-resistant design. It analyzes how factors such as the mechanical properties of structural materials, the form of the structure, the strength of connection nodes, and the conditions of the foundation affect structural damage. It proposes measures to enhance the seismic performance of concrete structures through ductility design, strength design, uniform design, and the strategy of multiple lines of defense. This study holds significant implications for the construction industry by offering a systematic set of earthquake-resistant design principles and strategies which can enhance the seismic resilience of existing and future structures, mitigating the damage caused by earthquakes. Moreover, for society at large, this research underscores the importance of reducing seismic disaster risks through scientific design, contributing to the protection of people's lives and property, and promoting sustainable societal development.
