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.
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.
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.
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 ...
Steel structures are considered mostly earthquake resistant but some failures have occurred. A great number of welded steel moment-resisting frame buildings, which looked earthquake-proof, surprisingly experienced brittle behavior and were hazardously damaged in the 1994 Northridge earthquake .

In earthquake engineering, vibration control is a set of technical means aimed to mitigate seismic impacts in building and non-building structures. All seismic vibration control devices may be classified as passive, active or hybrid [1] where: Base isolator being tested at the UCSD Caltrans-SRMD facility
The claim: Video shows effects of January 2025 earthquake in Taiwan. A Jan. 25 Facebook video (direct link, archive link) shows an array of disaster footage that includes high-rise buildings ...
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 ...
