Expansion Joints: Where, When and How - AISC Home

As a general rule, expansion joints should always be carried through the roofing membrane. Regarding the type of structural expansion joint, most engineers agree that the best expansion joint (and gener-ally the most expensive) is to use a line of double columns to provide a complete separation in the building frame at the joints.

Expansion joint - Wikipedia

An expansion joint is designed to allow deflection in the axial (compressive), lateral (shear), or angular (bending) deflections. Expansion joints can be non-metallic or metallic (often called bellows type). Non-metallic can be a single ply of rubberized material or a composite made of multiple layers of heat and erosion resistant flexible material.

Expansion Joint Covers - Floor, Aluminium, Structural ...

Expansion Joint Covers These structural movement can be defined as thermal and seismic.Thermal movement caused by temperature changes within the structure. Thermal expansion gaps are mostly smaller, falling in the range of 25mm (1”) to 75mm (3”) for horizontal as well as vertical movements occurring due to temperature changes occurred within the structure.

Control Joint vs. Expansion Joint Difference

The expansion joints are normally located between sections of bridges, paving slabs, railway tracks, and piping systems. The expansion joints are incorporated to endure the stresses. An expansion joint is simply a disconnection between segments of the same materials. In the block construction, the expansion joints are expressed as control joints.
