Earthquake engineering structures
- Earthquake engineering structures
Earthquake engineering structures are designed and constructed to withstand various types of hazardous earthquake exposures at the sites of their particular location.
Earthquake engineering is treating its subject structures like defensive fortifications in military engineering but for the warfare on earthquakes. Both earthquake and military general design principles are similar: be ready to slow down or mitigate the advance of a possible attacker.
The main objectives of earthquake engineering are:
* Understand interaction of structures with the shaky ground.
* Foresee the consequences of possible earthquakes.
* Design, construct and maintain structures to perform at earthquake exposure up to the expectations and in compliance with building codes.
Earthquake engineering or earthquake-proof structure does not necessarily mean "extremely strong" and "expensive" like the El Castillo pyramid at Chichen Itza shown above.
Currently, the most powerful and cost-effective tool of the earthquake engineering is base isolation which makes use of passive structural vibration control technologies.
