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.
The twin towers that were part of the original World Trade Center in New York City, New York until 2001 are also very iconic, although infamous due to the September 11 attacks. Twin towers also recur in Chinese construction, where, while the structures still representing a relative rarity, architects and engineers have developed novel ...
As a result of studies into the shinbashira structure and its utility in earthquake-resistance it has, once again, come into use in new buildings and structures, including the Tokyo Skytree. A central feature of the Tokyo Skytree tower is an innovative system to control swaying used here for the first time; it has been dubbed a "shinbashira ...
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.
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.
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 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 ...
Its resistance to earthquake is attributed to the combination of heavy mass (used for thermal insulation) and timber-frame structure. [5] The lattice design of its framework also provides the quincha building stability, allowing it to shake during an earthquake without damage.
