Ten major seismic strengthening materials

From the point of view of building materials, seismic building materials must have the characteristics of light, high strength and high toughness, such as wood, light steel, steel, reinforced concrete and composite material.

What are the seismic materials?

From the point of view of building materials, seismic building materials must have the characteristics of light, high strength and high toughness, such as wood, light steel, steel, reinforced concrete and composite material. 


  • Rebar of memory alloy SMA bar

    At present, this material has been applied in a bridge construction in Seattle, and is co constructed by University of Nevada, the State Department of transportation and the federal highway administration. Using the pseudo elastic and dynamic damping properties of SMA, SMA can be used in the passive control structure to play an aseismic role. It is also applied to active damping control of structural vibration.


  • Flexural concrete composite material

    The new type of super strong toughness fiber concrete, called "ECC", is a new type of engineering water based mud based composite material, which is based on the principle of microphysical mechanics, which has the characteristics of strain hardening and multiple crack cracking.


  • Aerated concrete

    Aerated concrete (aerated concrete) is a good new type of building material. It has the following advantages: light weight, good insulation and heat insulation, high strength, good seismic performance, good processing performance, high temperature resistance, good sound insulation, mechanized construction and strong adaptability.


  • Reactive powder concrete (RPC)

    Reactive powder concrete (RPC) is a new building material with excellent mechanical properties and durability after high strength and high performance concrete. It has super high mechanical properties, excellent durability, low shrinkage and creep properties, and has seismic performance.


  • Steel fiber reinforced concrete

    Steel fiber reinforced concrete (RPC) is a new type of multiphase composite material, which is mixed with short steel fibers of randomly oriented distribution in common concrete. These disorderly and distributed steel fibers can effectively prevent the expansion of micro cracks in the concrete and the formation of macro cracks, and greatly improve the tensile, bending, impact resistance and fatigue resistance of concrete, which has good ductility.


  • light steel

    The best seismic performance is steel structure housing, followed by wooden structure housing, and then reinforced concrete structure housing. The brick structure houses are not earthquake resistant, and the reinforced concrete structures with light wall materials are both safe and anti-seismic, and save energy.


  • Wood structure

    In Japan, new technology is adopted to collect wood waste from buildings, add polyethylene, polypropylene and polyvinyl chloride to make new wood materials, and then produce new building materials by extrusion, molding and injection molding to replace traditional wood. The building of this material is safe, seismic and energy saving.


  • Carbon fiber composites

    For earthquake resistance, the floor is bonded with carbon fiber reinforcement. The reinforcement of concrete structures by carbon fiber composites is mainly based on the high strength, high modulus of elasticity, Gao Ying denaturation energy and the use of modified epoxy resin cementing materials to make carbon fibers and concrete structures well bonded.It is necessary to reinforce and strengthen the lack of longitudinal reinforcement, shear and torsion reinforcement of the original structure, thereby improving the bending, shear and torsional load-bearing capacity of the structure.


  • Carbon fiber material

    Architect Ma Ke Yan uses hybrid carbon fiber materials to transform an office building. This is the world's first commercial building with carbon fiber reinforced seismic functions.


  • Rubber

    Rubber is also a good aseismic material. The central part of the building is made of laminated rubber. When the crack is 6, the force of the building can be reduced to 1/2. Rubber not only protects the wood from moisture, but also cushioning the earthquake.
