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.
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 ...
Its resistance to earthquake is attributed to the combination of heavy mass (used for thermal insulation) and timber-frame structure. [5] The lattice design of its framework also provides the quincha building stability, allowing it to shake during an earthquake without damage. [6] [7]
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.
Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes.
Through the George E. Brown, Jr. Network for Earthquake Engineering Simulation (), researchers are studying the performance of base isolation systems. [16]The project, a collaboration among researchers at University of Nevada, Reno; University of California, Berkeley; University of Wisconsin, Green Bay; and the University at Buffalo is conducting a strategic assessment of the economic ...
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.
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 ...
