KEYS TO SEISMIC DESIGN

on
The seismic alarm sounds and 40 seconds are critical to evacuate the occupants of a building in the event of an earthquake. of an earthquake, but in that time, mainly those who occupy the first three floors are evacuated. floors, while it is preferable for the rest to remain inside the building in the areas designated by the structural assigned by the structural engineers and safety personnel, which is usually in areas away from the areas away from windows. 
The earthquakes that have occurred in Mexico's modern history have been a learning experience for the experience for the construction industry, which has been trying to build buildings that are more resistant to this type of natural phenomena, in order to minimize the damage both to its structures and to the to its structures and to the people who occupy them.


According to estimates by the government of Mexico City, the 2017 earthquake in the country's affected more than 22,000 homes and an estimated 40 buildings collapsed. 
To make buildings in Mexico more resistant to earthquakes, it is essential to use techniques and materials that ensure structural safety. Here are some key recommendations: 
  1. Seismic design: The design must comply with the Mexican Building Regulations and Complementary Technical Standards (NTC), which provide guidelines for buildings in seismic for buildings in seismic zones. 
  2. Use of appropriate materials: It is essential to use high quality materials such as reinforced steel and high-strength concrete. Steel, in particular, helps to better absorb seismic energy. 
  3. Deep foundation: The foundation is critical to the stability of the structure. A deep for the type of soil allows the building to better withstand seismic movement. 
  4. Structural Reinforcements: Elements such as shear walls and reinforced columns should be incorporated to help distribute the load and improve the stability of the building. 
  5. Seismic isolators: In more advanced projects, seismic isolators can be used to the impact of ground movement on the structure, allowing the building to "move" independently of the ground. independent of the ground. 
  6. Preventive Maintenance: Perform periodic inspections to ensure that there is no deterioration of the structural materials and to correct any damage that may compromise the the safety of the building. 
  7. Staff Training: Ensuring that engineers and contractors are trained in the latest seismic techniques is key to ensuring that projects are built to high safety standards.
These strategies help minimize the risk of collapse and protect both people and investments from earthquakes.
