What Goes Into Designing Of Earthquake-Safe Buildings
Natural calamities are unavoidable happenings and a potent calamity leaves behind massive destructive and threat to humans. One such natural disaster is an earthquake. An earthquake comes without any warning, and if it is of a threatening frequency, it levels buildings and towers to the ground leaving everything in the rubble. As such, it is crucial to construct buildings and properties that are earthquake safe and use materials that protect them from this seismic calamity.
There have been several cases of towns being razed to the ground and destruction of cities by a powerful earthquake. According to seismologists at the National Earthquake Information Center, there are almost 20,000 earthquakes that occur every year. Among these, around 16 come out as major harmful disasters, and some go undetected by people.
If you’re the one wondering about what goes behind in the construction of an earthquake-safe building, then check out these quick facts.
1.) Lesser Load on Floors
It is important to use lighter materials and focus the loads on sideways rather than the top to make a building earthquake safe. The roofs and floors should be of lightweight materials that don’t cause much damage to the building on collapse. A lighter structure will result in lesser loads for the foundation. The focus on the sideway load will ensure the walls take the shock waves. The walls should be strong enough to protect the frame from the shockwaves and prevent any damage to the building.
2.) Even Structure
The structure of the building should be even and regular so that it can move equally to absorb and disperse the shock waves without damaging the building. A building with an irregular structure tends to topple down on a powerful earthquake. If one side of the building is odd, it would take the force of the quake and would fall, making it risky for the building structure to sustain.
3.) Solid Foundation
A strong foundation is an important thing to consider while constructing an earthquake-safe building. A solid foundation would hold a large building structure and prevent it from any natural disaster. The strength of the foundation also guarantees a long term survival of the building. It is crucial to conduct efficient ground tests before laying the foundation of a building to analyse its reaction to a natural disaster like earthquakes. A deep foundation ensures a robust construction that stands firm during any calamity.
4.) Shear Walls
A shear wall is a practical construction design to build an earthquake-resistant house. They are support walls constructed near staircases and elevators and give better and strong support to the hollow spaces. Shear walls have the cross-bracing construction method.
5.) Base Isolator
The construction engineer can implement the base isolator methods to absorb the shock from the building during an earthquake. The base isolator construction method is a construction method where the building structure is separated from the base of the building by suspension systems. These systems built with steel and synthetic rubber act as efficient shock absorbers during an earthquake building.
5.) Cross Bracing
Cross bracing is a construction system used to strengthen the building structure with diagonal intersections. In this system, two different diagonals support constructed in an X shape. This system increases the building’s resistance to the seismic force by distributing the energy evenly and relaxing it to prevent the structure from collapsing. Along with that, many builders trust seismic solutions Victoria for installing high-quality seismic bracing that can withhold heavy structures like AC shafts easily.
6.) Introduce Multiple Construction Strategies
An efficient earthquake building has multiple construction strategies that keep the house safe and secure during the calamity. Construction developers can implement various strategies focusing on the strength, durability, longevity and construction materials to construct an earthquake-resistant building.
7.) Materials Resistance
While constructing an earthquake-safe building, the construction engineer should check the resistance of the materials. The materials should be of the finest quality and maintain uniformity to guarantee an even building structure. The materials should be strong enough to withhold the energy from the earthquake and hold the building firmly in place.
Materials like structural steel and reinforced concrete are most suitable for constructing earthquake-proof buildings. Structural steel is an excellent material and can withstand massive movement and stress caused by seismic activity. It is known for its durability and ductility properties and mostly used in constructing skyscrapers and earthquake-safe properties. Reinforced steel is concrete embedded with reinforced steel bars. The steel element in the concrete automatically gives it the power to be a strong material and withstand the stress in the building. Reinforced concrete is mostly collaborated with structural steel to create robust structures that can withstand any natural calamity.
Constructing an earthquake-safe building is not an easy thing. Construction designers and developers need to follow many compliances and use the right mix of materials to produce a property that can withstand any strong seismicity.
