Expansion joints are structural elements in buildings and large-scale engineering projects. They are important, as they help prevent damage caused by stresses and structural movements, contributing significantly to the structure’s long-term durability.  Their incorporation into structural designs is a proactive measure that aims to prolong the structure’s lifespan, as well as to minimise maintenance costs, and reinforce its safety.  Expansion joint placement and sizing are delicate processes which require t

Expansion Joints: Design, Calculation, and Applications in Structural Engineering

Expansion joints are essential structural elements in buildings and large-scale engineering projects. They help prevent damage caused by stresses and structural
movements, thereby ensuring the structure’s durability and long-term integrity. This paper presents the theoretical principles, relevant code provisions (CYS EN 1991-1-5),
calculation methodologies, and practical applications related to expansion joint design, reflecting best practices in modern structural engineering.
