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.
In January 1928, the first edition of the Uniform Building Code (UBC) was published, and included an appendix with non-mandatory matter with §2311 recommending a minimum lateral design force for earthquake resistance of V = 0.075W for buildings on foundations with allowable bearing pressures of 4,000 psf or more, and 0.10 W for all other ...
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]
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.
Beijing has 15 major active fault lines, more than double the previous count, according to a new geological survey commissioned by the government. A third were "strongly active", suggesting a high ...

EN 1998-1 applies to the design of buildings and civil engineering works in seismic regions. It is subdivided in 10 Sections, some of which are specifically devoted to the design of buildings. Section 1 of EN 1998-1 contains the scope, normative references, assumptions, principles and application rules, terms and definitions, symbols and units.
