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.

Finally, in the event of an earthquake, since the damage is concentrated over a relatively small area (the brace's yielding core), post-earthquake investigation and replacement is relatively easy. [11] An independent study concluded that the use of BRBF systems, in lieu of other earthquake systems, produced a savings of up to $5 per square foot ...
The Applied Technology Council is a nonprofit research organization based in California which studies the effects of natural hazards on the built environment and how to mitigate these effects, particularly earthquakes. It was founded through the efforts of the Structural Engineers Association of California in 1973. [1]
General Motors, and other automobile manufacturers, have also begun using side-post battery terminals, which consist of two recessed female 3/8" threads (SAE 3/8-16) into which bolts or various battery terminal adapters are to be attached. These side posts are of the same size and do not prevent incorrect polarity connections.
Remotely triggered earthquakes are a result of the effects of large earthquakes at considerable distance, outside of the immediate aftershock zone. [1] The farther one gets from the initiating earthquake in both space and time, the more difficult it is to establish an association. The physics of triggering an earthquake are complex.
American Battery Technology Company, formerly American Battery Metals Corporation, is a US-based battery recycling technology startup founded in 2011. [1] It employs a hydrometallurgical process to recycle batteries and a targeted extraction system to extract raw materials from primary resources.
For example, the tooling used must be easy to center, be easy for the changer to grab, and there should be a simple way to provide the tool's self-disengagement. Tools used in ATC are secured in tool holders specially designed for this purpose. [3] A chain-type automatic tool changer with swiveling arm and two grippers, installed on a mill
