Concurrent shake-table testing of two or more building models is a vivid, persuasive and effective way to validate earthquake engineering solutions experimentally. Thus, two wooden houses built before adoption of the 1981 Japanese Building Code were moved to E-Defense [5] for testing. One house was reinforced to enhance its seismic resistance ...
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.
Architects in earthquake zones are increasingly using base isolation, which involves putting buildings on huge flexible pads that can reduce violent shaking by up to 75%. ... overly disaster-proof ...
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. [59]
The building was built from the top down. The thirteen-story [2] core was built first then steel was hung from cables at the top and the 9 occupied floors were successively built downwards. [1] It is considered to be one of Vancouver's most earthquake-resistant structures. [citation needed] The building's address is 1333 W. Georgia Street.
Seismic base isolation, also known as base isolation, [3] or base isolation system, [4] is one of the most popular means of protecting a structure against earthquake forces. [5] It is a collection of structural elements which should substantially decouple a superstructure from its substructure that is in turn resting on the shaking ground, thus ...
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 ...
