Earthquake-resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes. While no structure can be entirely impervious to earthquake damage, the goal of earthquake engineering is to erect structures that fare better during seismic activity than their conventional counterparts.
One of the early examples of the earthquake design strategy is the one given by Dr. J.A. Calantariens in 1909. It was proposed that the building can be built on a layer of fine sand, mica or talc that would allow the building to slide in an earthquake, thereby reducing the forces transmitted to building.
But while no two seismic events are directly comparable, earthquakes of similar force in other parts of the world — like a 7.6 magnitude quake that caused the collapse of over 30,000 buildings ...
Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes.
Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes.With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged.
Seismic codes or earthquake codes are building codes designed to protect property and life in buildings in case of earthquakes. The need for such codes is reflected in the saying, "Earthquakes don't kill people—buildings do." Or in expanded version, "Earthquakes do not injure or kill people. Poorly built manmade structures injure and kill ...
In the wake of last week's devastating earthquake and tsunami in Japan, prospective home buyers may be asking themselves what about a house makes it more able to weather a natural disaster. There ...
Model of the seismically protective wooden structure, the "gaiola pombalina" (pombaline cage), developed for the reconstruction of Lisbon. A gaiola pombalina (Pombaline cage; Portuguese pronunciation: [ɡɐjˈjɔlɐ]) is a masonry building reinforced with an internal wooden cage, developed as an anti-seismic construction system in Portugal after the 1755 Lisbon earthquake and implemented ...
