Diaphragms. Diaphragms are the primary component of a building’s horizontal structure, including the floors and the roof. To earthquake-proof a building, diaphragms must be placed on their own deck and strengthened horizontally to share forces with vertical structures.
How Do Buildings Withstand Earthquakes?
The question of how buildings withstand earthquakes has been a source of fascination for scientists and engineers for centuries. As the world’s population continues to grow, more people live in areas prone to earthquakes, making the question of how to protect them from the destructive force of seismic activity more pressing. Despite the many advances in earthquake-proofing technology, the answer is complicated and depends on a variety of factors.
The first step in protecting a building from an earthquake is to understand the type of seismic activity that is likely to occur in the area. Different types of earthquakes produce different types of forces, and understanding the expected type of seismic activity will help determine which earthquake-proofing techniques should be used. After the type of seismic activity has been identified, the building must be designed to withstand the forces that will be generated by the expected seismic activity. This involves taking into consideration the soil type, the building materials, the weight of the structure, and the height of the building.
The next step is to choose the appropriate earthquake-proofing techniques. Different techniques can be used depending on the expected magnitude of the earthquake. For example, base isolators, which absorb the energy of the earthquake and reduce the impact on the building, may be appropriate for moderate to strong
