Earthquake Resistance Techniques
Outline
I. Introduction
A. There are three common earthquake resistant building structure techniques
1. Base Isolation
2. Energy Dissipation devices
3. Active Control Devices
B. Out of the three is base isolation technique the best for earthquake resistant buildings?
1. Rolling pads that move
2. The ground will shake, building will stay in place
Thesis statement: Base Isolation is the best technique Than othersfor earthquake resistant buildings.For the efficient,and The cost
Body:
*Active Control devices its control the extra energy of the earhquakes
1. Widely used in aerospace structures
2. Watches for the structures response to the earthquakes and have control against the earthquake.
3. Analysis
a. Still a work in progress
Might be better than Base Isolation after the researcher and experiences
According to the author.The active control can reduced the wave of earthquake to 6%.When we installed inside the building(Active Control Devices for Earthquake Resistance,2011).
As you see It has a good advantages its provide the building with strength and rigidity,but other techniques are more efficient and better.
In concluding it could be the new generation of earthquakes but it has more disadvantages than the other two techniques
**Energy dissipation devices
1. Diagonal braces with dampers absorb the shock from the earthquake
2. Like a car, it absorbs the shock and decreases the motion of the building
3. Analysis
More expensive than Base Isolation
Too much maintenance and fluid for one piston.
According to the author.When we install this devices we have less damage during an earthquake(Energy Dissipation Devices for Earthquake Resistant Building Design,2011)
As we see Energy d...

Earthquakes play a major role into understanding the composition and materials that exist within the Earth (Merali and Skinner, 2009, p.252). Earthquakes are the main source of insight into the inner workings of the earth, due to the nature of the seismic waves they produce. P and S waves are reflected and refracted at different boundaries within the earth, and this enables seismologists to make inferences about the internal composition and structural of planet Earth. (Merali and Skinner, 2009, p.252).
Problem Statement: Earthquakes are a natual part of the environment. They do,however,cause devistating effect on the environment. Since Earthquakes can not be avoided, maybe there is a way to determine when they are going to occur so precautions can be taken to get people to safety and protect as much of

The attacks of September 11 were some of the worst ever experienced in the history of the United States. These attacks generated a widespread feeling of insecurity and uncertainty throughout America, compelling the government to revise safety measures and protocol pertaining to the wellbeing of the United States. However, some aspects of security under modification, such as building codes, are being questioned by many. The collapse of the twin towers, due to the impact from the airplanes, spurred a movement focused on strengthening the integrity of skyscrapers and other high-rise buildings throughout the United States. Though the terrorist attacks proved to be a tremendous tragedy, the application of measures this great is not seen as a proven necessity. The circumstances of the incident proved to be so extraordinary that dramatic modifications to the structure of building should not take place because of such an event. Therefore, the building codes of skyscrapers should not be changed due to the terrorist attacks of September 11.

Today, engineers rely on damping systems to counteract nature's forces. There are many types of damping systems that engineers can now use for structures, automobiles, and even tennis rackets! This site focuses on damping systems in structures, mainly architectural variations of the tuned mass damper.
The failure of beam-to-column connections in steel Special Moment Resisting Frames had the most to do with most of the damage in these buildings. In response to the pattern of buildings including SMRF's, there have been studies to improve the design and construction practices to allow for better and more improved buildings. The higher building codes wanted engineers to find new ways to allow homes, apartments or skyscrapers the ability to sustain a powerful earthquake. These engineers borrowed the model from New Zealand engineer Bill Robinson. His method was to use lead-rubber bearings, which minimize the vibrations caused by the earthquake, improving its performance during seismic activity. Many of the old buildings that took damage during the earthquake had to be retrofitted. This was done by either infilling the walls, adding braces, adding buttresses, adding new frames, exterior or interior, completely rebuilding or isolating the building. All of these techniques of retrofitting a building all add extra support to the remainder of the building. Most of the residential structures that took damage and were deemed uninhabitable were the apartments or condominiums that were made of light, wood frames. Also, many houses made using stucco took extensive damages. This was due to the fact that the stucco was not properly installed in the first place,

After doing extensive research on Haiti’s earthquake and their shelter design, we decided these several facilities are most innovative and adaptable to Haiti and its condition. We have distinctly identified our innovative shelters into temporary and permanent. Temporary Shelters JAS – “Just Add Sticks” Transitional Shelter This inexpensive, versatile frame connector system, when used in conjunction with local or delivered bamboo, roofing and wall membranes, provides 18m2 of covered space. Simple assembly of familiar “3-4-5” truss-roof frame modular design allows World Shelters JAS to be made in multiple sizes.
Protecting your possessions against earthquake damage isn’t something most people spend a lot of time thinking about, but personal storage area preparation prior to an earthquake can help ensure your possessions don’t incur costly damage.
Earthquakes are vibrations felt at the surface of the earth which are caused by disturbances of the energy in the earth's interior. These vibrations are known as seismic waves. (Skinner Robinson McVerry 1) There are different type sof seisimc waves such as Primary (P) waves, whcih travel the fastest, Secondary (S) waves which cause the earth to vibrate vertically, Surface (L) waves. P and S waves are "affected by changes in the density and the rigidity of the materials through which they pass." (Columbia Encyclopedia) Earthquakes vary in their intensity and duration. Often times they are strong enough to cause massive destriction. Tall buildings often suffer as a result of these natural disasters. In recent years this has become a larger and larger threat with both the number of large buildings, and their number of occupants increasing. In an effort to try to minimize the damage caused by earthquakes many some engineers focus primarily on designing and constructing earthquake resistant buildings. Earthquake engineers have gathered much of their information from analyzing past earthquakes, and learning which buildings can and can't withstand the tremors. The goals of these engineers is to design buildings that can withstand moderate earthquakes and obtain minimal damage, and that the buildings will not collapse lowering the probability of human deaths.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
