The phrase "earthquake architecture" is used to describe a degree of architectural expression of earthquake resistance or implication of architectural configuration, form or style in earthquake resistance. It is also used to describe buildings in which seismic design considerations impacted its architecture.
AeDES (Agibilità e Danno nell'Emergenza Sismica) is a printed Rapid Post-Earthquake Damage Evaluation form, from GDNT (Italian national seismic protection group). It is used by Italian qualified civil engineers to assess the structural damage of buildings after an earthquake. The AeDES Form is used from the civil protection technical staff ...
This mode of ground failure, termed lateral spreading, is a principal cause of liquefaction-related earthquake damage. [43] Beams and pier columns diagonal cracking, 2008 Sichuan earthquake. Severely damaged building of Agriculture Development Bank of China after 2008 Sichuan earthquake: most of the beams and pier columns are sheared.
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.
As seen in the figure, a building has the potential to 'wave' back and forth during an earthquake (or even a severe wind storm). This is called the 'fundamental mode', and is the lowest frequency of building response. Most buildings, however, have higher modes of response, which are uniquely activated during earthquakes.
Smoke billows from the port of Iskenderun, Turkey, on Feb. 7 after an earthquake. (Burak Kara/Getty Images) (Getty Images) “The primary reason for earthquakes is the relative movement of ...
Partial soft story collapse due to inadequate shear strength at ground level during the Loma Prieta earthquake.. A soft story building is a multi-story building in which one or more floors have windows, wide doors, large unobstructed commercial spaces, or other openings in places where a shear wall would normally be required for stability as a matter of earthquake engineering design.
For example, after a 4.8 magnitude earthquake hit New Jersey in April, people in the affected areas reported symptoms including dizziness, vertigo, nausea and just generally feeling a bit off.
