Expansion joints can be categorized into three types: expansion joints, settlement joints, and seismic joints.
Expansion joints: Due to changes in temperature and humidity, building components may undergo expansion and contraction. To address this, vertical gaps are typically set at appropriate locations in the structure, separating the walls, floor slabs, and roofs from the foundation, thus creating several independent sections of the building. Expansion joints set to overcome excessive temperature differences may not require a break at the foundation; instead, they run from the top of the foundation to the roof along the structure.
Seismic joint: A gap designed to make buildings more regular and to enhance structural seismic resistance, with the foundation remaining unbroken. Its purpose is to divide large buildings into smaller sections, creating relatively independent seismic units, to prevent overall building vibrations from becoming discordant due to earthquakes, thereby avoiding damage.
