Prefabricated Steel Structure is the Best Earthquake-Resistant

If we talk about the building material, then prefabricated steel structure is considered the best earthquake-resistant. No doubt, natural hazards cannot be avoided but one can make efforts to minimize their negative consequences. The most adverse damages are caused by earthquakes; therefore it is essential to take necessary steps against it. You will be amazed to know that prefabricated steel structure can work drastically against the earthquakes. If you want to construct a building in an area where earthquakes are common then prefer hiring a prefabricated workshop supplier.

 

Why it’s important to pay attention towards building material?

Whenever you desire to construct a building, you should consider its structural strength. Unlike winds, earthquake vibrations impact the building structures in both horizontal and vertical direction. Fluctuation in the building can occur by these vibrations, which relies upon the variation between earth’s fluctuations period and the building’s own fluctuation period. If both these periods are close to each other, then there will be a larger force from earthquake along with forceful resonance effect. The building’s force depends on the construction’s capacity to absorb and disburse earthquake energy. Let’s have a look at the real-life example.

In 1994, an extreme earthquake (Richter scale 6.7) hit Northridge, California. A widespread damage was caused as a result of this earthquake. However, no damage was reported for the steel buildings. Consequently, the demand for steel buildings was increased to a greater extent. So, it is very important to use an earthquake-resistant material in the construction work in order to protect your building against earthquakes.

 

Testing the pre-engineered/prefabricated steel structure

There was a need for earthquake simulations to exhibit the effectiveness of pre-engineered/prefabricated steel structure during tremblers. In 2010, the Metal Building Manufacturers Association, the Network for Earthquake Simulation, University of California, and American Iron & Steel Institute teamed together to test pre-engineered/prefabricated metal buildings. In order to reproduce the correct trembling and duration of particular earthquakes, large hydraulic rams hit 3 base tables. 3 kinds of 60'×20'×20' pre-engineered metal frames become the biggest outdoor testing platform for earthquake.

The first frame was made up with steel framing bay along with girts, steel sheathing, and purlins on the sidewalls and roof. The second frame was created with pre-cast concrete walls, and the third one was made with both pre-cast concrete walls and mezzanine system. Sensors were incorporated with each of these frames to measure the upshots of simulated earthquakes. The reason behind this testing was to figure out the earthquake magnitude that is required to slump each structure.

None of the 3 tested frames was collapsed despite the fact that they were pushed into maximum limits. A minor deformity in the rafter happened at 250% of the actual earthquake’s strength, but still, the structure remained intact.

 

Final Verdict

Keeping in view the result of tests, it is highly recommended to use a pre-engineered steel structure for all sorts of buildings. But make sure to hire the best prefab building manufacturers in your area. You can choose Foshan Shengbang Steel Structure Co., Ltd. as it offers a broad range of earthquake-resistant steel structures.
