Staff Writer Apr 03, Long considered an essential material for construction projects around the world, steel is only just now becoming known as a particularly important way to diminish earthquake damage on finished structures. Conventional wisdom in the first half of the 20 th century was the heavier a building was, the safer it would be in the face of an earthquake; however, recent architectural studies have found that buildings made out of materials like concrete or bricks are actually how to cook a turkey for thanksgiving recipes a disadvantage when experiencing an earthquake.
As the earth moves, the weight of the building slams against the structural pieces from side to side. Therefore, the heavier the building, the more force it exerts on these structural elements, and the more likely it is to come crashing down.
However, buildings consisting primarily of steel or other metals are much better at resisting earthquakes. Steel is much lighter than concrete, but it still brings a great deal of durability to construction projects.
More flexible than concrete and other building materials, steel is more likely to bend instead of break when experiencing seismic force. Because of these attributes, buildings constructed primarily from steel require less earthquake proofing than those made from other materials.
Additionally, steel buildings require fewer repairs after earthquakes, lowering maintenance and insurance costs for how to be an artist project. There are several ways to incorporate steel into your latest project to increase resilience against earthquakes:.
Metal is growing in popularity as a cost-effective way to meet stringent earthquake codes while producing aesthetically pleasing structures. Cities from San Francisco to Tokyo to Santiago, Chile, are seeing massive investment in metal architecture because of its ability to resist earthquakes and stand the test of time.
Earthquake-resistant Foundations and Materials
Concrete buildings, which are normally brittle (relatively easy to break), can be made ductile by adding steel reinforcement. In buildings constructed with steel-reinforced concrete, both the steel and the concrete must be precisely manufactured to achieve the desired ductile behaviour. Sep 13, · And buildings made of structural steel-- steel components that come in a variety of preformed shapes, such as beams, angles and plates -- offer the highest ductility, allowing buildings to bend considerably without breaking. Ideally, engineers don't have to rely solely on a structure's inherent ability to dissipate energy. Jun 20, · One of the best earthquake resistant buildings materials is steel-reinforced concrete, as the steel embedded increases ductility. The best shape can be constructed out of structural steel, such as angles, beams and plates, so that the buildings can bend considerably without breaking.
According to scientists, there may be more earthquakes than usual in As part of t he Geophysical Research Letters presented at the Geological Society of America , scientists tracked major earthquakes with a magnitude greater than 7 from to They found distinct and repetitive intervals at which the average number of earthquakes per year was much higher than other years.

As structural damage is the leading cause of injury and deaths during an earthquake, architects, engineers and builders need to make sure buildings are built with the right materials and design. The most dangerous type of earthquakes are ones that trigger horizontal movements, because tall buildings are better at resisting vertical loads than horizontal ones.
These ground motions can damage building foundations in a matter of minutes, causing severe injuries and deaths.
Building a structure to withstand seismic waves starts with the right materials with the right properties, and steel is by far the most widely used material for building earthquake-resistant buildings.
According to the World Steel Association , ductile buildings are safer as they dissipate energy from seismic waves. A building will typically have ductile parts that can undergo plastic deformations without complete structural failure during an earthquake. Steel is the most common type of material for such parts. Moreover, due to the law of inertia, the lighter the building, the less force seismic waves will exert on the building. On average, multi-story steel buildings are 60 to 70 percent lighter and 10 times stronger than concrete-framed buildings of the same size.
With steel, builders can add vital designs and reinforcements to keep the structure standing through an earthquake. Cross braces transfer the force of an earthquake to the ground.

Builders can also reinforce the walls of buildings with additional vertical walls, or shear walls, that add stiffness to the frame of the building, allowing it to resist swaying or horizontal movements. Base isolators absorb much of the shock of seismic waves. Source: Embelton. Base isolation involves separating the building from the foundation so that the isolators to absorb shock from the earthquake. The isolators allow the building to move at a slower pace because they dissolve a large part of the shock.
Although more costly, moment-resisting frames enable buildings to withstand an earthquake with excessive horizontal movement. The homes also incorporate PosMAC, a specialized galvanized steel that is 5 to 10 times more corrosion-resistant than standard steel and is more durable and affordable. Because all the Steel Houses survived the Gyeongju earthquake while other homes were damaged, more and more people in Korea are choosing steel for their homes over traditional building materials such as wood and concrete.
The same trend can be observed in Japan, where earthquakes are much more frequent. In order to build more earthquake-resistant buildings, steel is still the best solution available.
