Tips for Building an Earthquake-Resistant Structure

Natural disasters can be devastatingly strong and sudden, posing a threat to communities across the country. Although professionals have developed the ability to predict some disasters like tornadoes and blizzards as a matter of course, others are still possible without warning. Any magnitude of an earthquake can happen at any time of year, with little warning. They can strike small, remote areas or devastate large cities. 

Although experts have identified specific areas in the United States that are most susceptible to earthquakes, they can happen anywhere. The greatest danger of widespread destruction is possible in a country filled with concrete, steel, and glass.

Federal Emergency Management Agency (FEMA), in collaboration with the National Earthquake Hazards Reduction Program, (NEHRP), researches and designs structural building practices and regulations that protect against earthquakes. They aim to reduce injury and damage through the building’s structural integrity. You can take the measurement of the area using an area calculator.

FEMA and NEHRP safety specialists work together with architects and engineers to identify building characteristics that directly impact a building’s behaviour in vibrations and shakes.

What are Earthquake-Resistant Buildings?

Earthquakes can be described as rapid shaking of ground due to the shifting of rocks and tectonic plates below. Although the ground appears solid, the earth’s upper crust is very deep and can cause pressure to build up between plates and cracks over time. Seismic vibrations and shaking can immediately affect miles of land when the pressure is released. Additional damage can be caused by aftershocks that may occur after the initial earthquake. In order to measure the land area, you can use the land area calculator.

Although earthquakes can occur anywhere in the United States, the most at-risk areas are California, Oregon and Washington. These areas are subject to stricter, higher-quality building standards. To minimize damage and protect people and property, buildings might need to withstand foundation shifts and radical movement. No emergency plan can save people from injury if the building collapses or fractures. These characteristics are important in earthquake-resistant building designs: regularity, stiffness, strength, redundancy and foundations.

  • Stiffness and strength

Safety professionals recommend that buildings be designed to resist earthquakes and have adequate lateral and vertical stiffness. Structures are better at handling vertical movement from earthquakes than they are for horizontal or lateral movement. 

Professionals still pay attention to a building’s vertical stiffness, strength, and ability to support itself without considering earthquakes. But earthquakes can bring new directions that you may not have anticipated. The earthquake will cause buildings to shift in all directions and, if they are not constructed properly, can quickly destabilize.

  • Regularity

This characteristic describes the movement of a building when it is pushed in lateral directions. Safety professionals and building designers expect the building to move evenly so that energy is dissipated without placing too much force on any one side. A building that is not straight will show its weaknesses when it sways. This weakness can compromise the structure and cause concentrated damage, which in turn compromises the entire structure.

  • Redundancy

Redundancy is one of the most crucial safety features when designing for safety. It ensures that there are multiple strategies in case one fails. Although they can increase the cost of building, redundancies are worth it in case of an earthquake or other natural disaster. Safety professionals recommend equally spreading strength and mass throughout the structure to ensure strength is not dependent on anyone factor.

  • Foundations

Stability is an important characteristic of building large structures, regardless of the risk of natural disasters. A strong foundation is essential for the long-term survival of a building. It can also help to resist powerful earthquake forces. Each area has its own foundational characteristics, which dictate how the structure’s base should be strengthened. 

Before building, professionals must closely monitor how the ground reacts to and moves. Deep foundations are used to support buildings that can withstand earthquakes. These foundations are connected together so that they can move together to stabilize such drastic measures.

  • Continuous Load Path

To ensure that inertial forces are dissipated, it is important to tie into the stable foundation characteristic. Instead of the foundation being smashed by a quake, multiple points of strength and redundancies can share the force. 

This is what safety professionals, engineers, and architects must be aware of when designing. The structure will collapse if it isn’t properly connected. The earthquake’s path through the building is called the continuous load path. It runs vertically and laterally. The path must be intact in order to dissipate powerful earthquake shudders.

Although earthquakes are less common than other natural disasters such as hurricanes and tornadoes, building earthquake-resistant buildings can protect you from all kinds of natural disasters. When developing structural integrity protection strategies, safety professionals make people’s safety their top priority. 

Safety professionals often work in close collaboration with other professions to create earthquake-resistant building provisions. Safety professionals must be able to understand multiple factors and work with other professionals to come up with the best solutions.
