Earthquake Engineering

Earthquake engineering involves designing buildings and other structures to withstand the effects of earthquakes. The theories of earthquake engineering can be applied to new construction or existing structures that can be retrofitted. The possible threat to the structure has to be assessed based on past earthquake activity in the area, the type of ground the building stands on, and the materials used in construction.

A number of different engineering techniques can be used to keep buildings safe, depending on the type of structure. Skyscrapers sometimes have shock absorbers, just like cars. Another technique involves placing a large tank of water high in a building. The water acts as a weight that counters the resonance that can tear a building apart. Other strategies include reinforcing the foundations or building in a concealed system of weights can keep a building from sustaining major damage.

Components of Earthquake Engineering
Shorter buildings that don't have steel skeletons are actually more vulnerable than skyscrapers. Homes are often fairly safe if their attachment to their foundations has not been overly degraded. Earthquake engineering experts should be brought in to inspect and repair all kinds of structures so that future earthquake damage can be minimized. This includes making sure that the structural protections will last for many years and offering recommendations for future preventative maintenance.

It is not usually cost-effective to make any building completely earthquake-proof. Designs for buildings in seismically active areas plan for certain areas of the building to be damaged, while preventing a full collapse. As long as the structure protects the people inside and allows them to exit safely, the building can be repaired or torn down and replaced later.
