Buckling Restraint Brace Concrete -filled Steel Tube (CFT)

Japan Iron and Steel Federation – Japan

Disaster protection building is a steel structure in quake resistance and tsunami resistance applying buckling restrained braces and concrete-filled steel tube members.
This building has superior earthquake-proof and tsunami-proof safety as well as versatile use of space.

Characteristics

Enhanced Tsunami-Resistant Safety
– Pilotis structure designed to exceed the height of the estimated tsunami level ensures structural resistanceagainst tsunami forces.
Improved Seismic Performance
– Buckling Restrained Braces integrated into the superstructure enhance vibration control and seismic resilience.
Flexible Spatial Configuration with Long-Span Design
– Steel structural system enables long-span layouts, allowing flexible space planning with minimal column interference.
Shortened Construction Period and Simplified On-Site Work
– Compared to reinforced concrete structures, steel construction allows faster build times and facilitates
immediate restoration or reconstruction.

Applications

For example,
Government building
Disaster prevention base

A hybrid panel construction method composed of “wall panel,” “floor panel,” and “roof panel,” in which steel (sheet metal light gauge sections) and structural face materials (such as structural plywood and plasterboard) are used.

School Facility Built with a Steel Structure [Multipurpose institution]

It has flexibility in dealing with future changes of space usage because a large space without column can be provided.

Weathering Steel for Bridges

By adding elements such as Cu, Cr, and Ni that are effective in improving weather resistant performance, a protective rust is formed on the surface of the steel material, suppressing the progression of corrosion.
