The different structural measures work together to make a building earthquake-resistant in a few ways. First, they help to distribute the forces of the earthquake throughout the building. This helps to prevent any one part of the building from being overloaded and collapsing. Second, they help to absorb the energy of the earthquake. This helps to reduce the amount of shaking that the building experiences. Third, they help to prevent the building from tipping over.

Here is a more detailed explanation of how each of the structural measures works:

* **Reinforcing the structure with steel**. Steel is a strong and flexible material that can help a building withstand the shaking forces of an earthquake. When steel is used to reinforce concrete, masonry, or wood structures, it helps to make the structure more ductile. This means that the structure can deform without breaking, which helps to absorb the energy of the earthquake.
* **Using shear walls**. Shear walls are vertical walls that help to resist the horizontal forces of an earthquake. They are typically made of concrete or masonry and are often reinforced with steel. Shear walls work by transferring the horizontal forces of the earthquake to the foundation of the building.
* **Using moment-resisting frames**. Moment-resisting frames are a type of structural system that uses beams and columns to resist the forces of an earthquake. The beams and columns are connected in such a way that they can bend and flex without collapsing. This allows the building to absorb the energy of the earthquake without being damaged.
* **Using base isolation**. Base isolation is a technique that uses flexible pads to separate a building from its foundation. This allows the building to move independently of the ground during an earthquake, reducing the amount of shaking that the building experiences. Base isolation is a very effective way to make buildings earthquake-resistant, but it is also the most expensive.
* **Using ductile materials**. Ductile materials are materials that can deform without breaking. Concrete and steel are both ductile materials that can be used to make earthquake-resistant buildings. Ductile materials are important because they can absorb the energy of the earthquake without being damaged.
* **Designing for redundancy**. Redundancy is the use of multiple structural elements to support a load. This helps to ensure that the building will not collapse if one element fails. Redundancy is an important design principle for earthquake-resistant buildings.
* **Using seismic codes**. Seismic codes are regulations that specify the design and construction requirements for earthquake-resistant buildings. These codes are developed by earthquake engineers and are based on the seismic hazard of the region where the building is located. By following seismic codes, builders can help to ensure that their buildings are safe from earthquakes.

By taking all of these measures, it is possible to make buildings more resistant to earthquakes and reduce the risk of damage and injury.
