Codes are not designed to make buildings earthquake proof in the sense of them suffering zero damage. The goal of most building designs is to reduce earthquake damage to a building such that it protects the lives of occupants and thus tolerance of some limited damage is accepted and considered a necessary trade-off. A supplement or precursor to ...
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.
2.5 to 5.4: Minor or no damage. 5.5 to 6.0: Slight damage to buildings. 6.1 to 6.9: Serious damage. 7.0 to 7.9: Major earthquake. Serious damage. 8.0 or greater: Massive damage, can destroy ...
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.
Before and after pictures reflect the true scale of the devastation. The Grand Mosque in Malatya, Turkey is among the buildings damaged. Before (top) and after (bottom) satellite images show ...
Scenes of buildings reduced to rubble were beamed around the world this week following a 7.5 magnitude earthquake that struck Ishikawa prefecture on Japan’s western coast on Monday. The full ...
An unreinforced masonry building (or UMB, URM building) is a type of building where load bearing walls, non-load bearing walls or other structures, such as chimneys, are made of brick, cinderblock, tiles, adobe or other masonry material that is not braced by reinforcing material, such as rebar in a concrete or cinderblock.
