Can light steel villas withstand earthquakes?

  Modern architecture is increasingly industrialized and standardized, and light steel villas are one such example. The fact that light steel villas are constructed without using any bricks or tiles makes many people feel insecure, worrying that such houses are uninhabitable. Let's take a look at what makes this type of housing so special and whether it can truly withstand the test of time! 

  Light steel structure houses are primarily constructed from light steel keels made by cold-rolling hot-dip galvanized aluminum steel strips. The aluminum-zinc alloy structure of the aluminum-zinc coated steel sheet is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, cured at 600℃. The entire structure, consisting of aluminum, iron, silicon, and zinc, forms a dense quaternary crystal, creating a strong and effective barrier against corrosion.

Light steel keel 

  The steel surface of light steel keel structures undergoes special anti-corrosion treatment, primarily aluminum-zinc plating and zinc plating. According to relevant data, this anti-corrosion layer can protect the structure for 300 years, far exceeding the service life of national permanent buildings. A CCTV program, "Approaching Science," once conducted an experiment showing that aluminum-zinc-plated light steel performed well in a salt spray test. Many netizens were surprised and expressed disbelief, leading to heated debate in the comments section, with many saying that stereotypes are unreliable.

  Reinforcing steel: Reinforcing steel without any protection rusts immediately.

  Ordinary heavy steel: Ordinary heavy steel with a simple coating, which is severely corroded.

  Light steel: Only light steel coated with aluminum zinc has a smooth surface without any rust marks.

Seismic performance 

   Light steel structure buildings are lightweight, and most of the components of the light steel walls are mechanically connected using self-tapping screws, which determines the inherent seismic resistance of the light steel structure system. Since earthquakes involve lateral and vertical movement, the light steel structure, fastened together, forms a safe and stable box, preventing wall collapse or floor collapse that could endanger personal safety during an earthquake. It meets the requirement of not collapsing even in an earthquake of magnitude 9.
