PCM-Filled Brace

PCM-Filled Brace with Energy Dissipation via Phase Change Material Layer

This technology features a brace composed of a hollow polygonal tube, a core member with a T, I, H, or + shaped cross-section housed within the tube, and a PCM layer where a phase change material is filled and integrated between the tube and the core.

Conventional braces, often used as concrete reinforcements, are heavy and difficult to adjust in length to accommodate variations in steel structure dimensions.

This technology achieves a lightweight design using a phase change material layer and allows for on-site adjustment and filling of the core, enabling stable energy dissipation in steel structures regardless of dimensional variations.

Key Features:

• A brace tube formed with a polygonal cross-section and a hollow interior.
• A core member housed within the tube, featuring a T, I, H, or + shaped cross-section.
• A core member equipped with end plates at both ends for connection to steel structures and a polygonal hollow hole inside.
• A PCM layer where phase change material is filled in the space between the tube and the core, integrally connecting the inner surface of the tube and the outer surface of the core.
