Earthquakes are amongst the most devastating natural disasters across the world. And considering the fact that we can't prevent them, the only strategy we can put forth is preparedness. To tackle this challenge, engineers and architects have developed and designed numerous structures that can withstand even the strongest quakes. These structures are designed using cutting-edge engineering techniques and materials to mitigate the adverse effects of earthquakes. In this article, we’re going to discuss the top 10 earthquake-resistant structures to visit and explore in the world.
Burj Khalifa, towering at 828 meters in length, is the tallest structure in the world. It is also one of the most engineered buildings on the planet. It has a robust foundation that can withstand seismic activity, including earthquakes caused by proximity to tectonic activity.
Taipei 101 is a 101-story skyscraper located in Taiwan that was designed to resist strong earthquakes and typhoons. It can withstand winds of up to 450 kph, and its architecture comprises advanced damping systems and tuned mass damper. Its form eliminates the requirement for any external steel bracing, significantly improving its earthquake performance.
Transamerica Pyramid is one of the tallest buildings in San Francisco, and perhaps one of the most fascinating buildings in the city. The building's exclusive earthquake-resistant design comprises calibrated steel support columns with a stiffness of more than 200 times the average of traditional high-rise buildings.
Tower 1 and Tower 2 of the Petronas Towers stand at 452 meters above the ground, making them one of the tallest buildings globally. The towers have a unique design that significantly elevates their ability to withstand strong winds and earthquakes. The structure comprises a steel-rod-in-concrete core that offers excellent stability and safety.
The Shard is the tallest building in Western Europe, standing at 310 meters. The building has a slender shape, which optimizes its resistance to both seismic and wind forces, which are typically the main causes of substantial structural damage during earthquakes. The floor-to-ceiling windows also play a vital role in the building's structural integrity.
The Marina Bay Sands is a three-tower building in Singapore with a 2,561-room hotel, a convention center, a shopping mall, and a casino. The structure comprises three 55-story towers connected by a skybridge that features a viewing platform. The foundation design includes significant piling that reduces the seismic risk in Singapore's earthquake-prone regions.
The Tokyo Skytree is a telecommunication tower located in Tokyo, Japan. The structure was designed to withstand powerful earthquakes and typhoons that frequently affect the country. The tower's base is reinforced with massive blocks of concrete, and its height is primarily supported by steel columns that function as wind- and earthquake-resisting systems.
One World Trade Center or Freedom Tower is the tallest structure in the United States, standing at 541 meters. The building was designed using state-of-the-art safety and security strategies, including state-of-the-art fire safety systems, advanced exit strategies, and robust foundation designs that help it withstand the most severe seismic events.
Hoover Dam is a hydroelectric dam located in the United States along the Colorado River. The dam is designed to withstand even the most severe earthquakes thanks to its gravity arch design. The dam's base thickness and its ability to resist overturning ensure that the dam can safely withstand natural disasters like earthquakes and floods.
The Bank of China Tower in Hong Kong has become an iconic building thanks to its unique shape and design. Designed by Chinese-American architect I. M. Pei, the tower's innovative design enhances its resistance to wind and seismic activity.
Yes, all buildings can be designed to resist earthquakes, especially if they are erected in a region prone to earthquakes. Developers and designers use various techniques, including installing proper foundations and creating the structure's interior building core to create earthquake-resistant structures.
Engineers and architects use numerous techniques to create earthquake-resistant structures. The most commonly used method is connecting the building's foundation to bedrock or stable soil, implementing base-isolation mechanisms, developing a robust and ductile structure frame, and creating resistance through bracing, dampers, and deformable elements.
Earthquake-proofing a building means designing it to withstand strong ground shaking without any damage. While it's challenging to make any structure completely earthquake-proof, developers and designers focus on creating earthquake-resistant designs that minimize any damage caused by strong earthquakes.
You can check the building's building code to see if it fulfills the necessary earthquake-resistant standards. Additionally, you can check the building's foundation to see if it’s connected to the bedrock. You can also review the structure’s blueprints to determine if it features the latest earthquake-resistant techniques suggested by experts.
Steel-reinforced concrete is one of the most commonly used materials in earthquake-resistant structures. Other materials include buckling-restrained braces, dampers, fiber-reinforced polymers, high-performance steel, and cross-laminated timber.
Yes, it’s possible to retrofit an existing building to make it more earthquake-resistant. Retrofitting techniques include adding shock-absorbing fittings to the building’s foundation, anchoring the roof to the outer walls, adding steel bracing, and installing dampers or another energy-dissipating material.
The structures listed above signify the excellent engineering techniques and materials used to construct modern earthquake-resistant buildings. Engineers and architects have worked together to craft structures that can resist natural disasters, ensuring the safety and security of those inside. In the light of recent natural calamities across the world, it is becoming increasingly crucial to have buildings that can withstand environmental emergencies, earthquakes being one of them. Building such buildings is important to the development of our cities and societies, and we must continue to innovate and improve our building technologies to create even safer and more earthquake-resistant structures.
