When it comes to the terrorist attacks of September 11th, people assume that there is an obvious reason why it happened. These people believe that because an airplane crashed into the building the towers fell over. What people tend to over look when it comes to causes of disasters are the things that lead up to it. In my opinion there were many things that could have been done to prevent the attacks of that fateful day. In this case I am not talking about preventing the event from occurring but I am talking about preventing the tower from falling down. There are things that could have been done leading up to during and after the attack that would have prevented the towers from tumbling down. Anything and
In 2010 there was an earthquake that affected many cities and a Chilean firefighter said that, “The earthquake was 8.8 and there were 6,000 buildings in the affected area – yet only six were seriously damaged, and of those, only four had to be demolished”(Soichet, Romo). An 8.8 is outstanding and the fact that only a small amount of buildings were damaged is jaw-dropping. Insurance is also a very crucial in earthquakes. People invest in earthquake insurance and this helps because even if homes are destroyed, nobody will be displaced within their own country. “In Chile, an estimated 10 percent of residential properties and 60 percent of commercial properties are insured against earthquake damage”(). Another way chile has adapted with their buildings is the new building codes. The building codes are very strict and any and every commercial building has to be able to manage an earthquake with a magnitude of 9.0. “The building can crack, tilt and even be declared unfit for future use – but it must not collapse”(Franklin). This ensures that people will be safe in buildings if there is an
When a large magnitude earthquake strikes, roads might buckle, dams sometimes fail, and buildings can collapse. As more earthquakes occur, building regulations have been altered to ensure that buildings experience minimal damage. The Trans-Alaskan Pipeline System (TAPS), which transports oil from Prudhoe Bay to the Gulf of Alaska, had engineering in place so when the earthquake struck the Denali fault in Alaska in 2002, the pipeline didn’t leak any oil (Nyman, Johnson, and Roach, 2003). The success of the pipeline came from its supporting structures. The engineering used in the TAPS should be applied to buildings in areas that are also prone to large magnitude earthquakes, such as Washington and California. California is home to the San Andreas fault, a major transform fault, just like the Denali, and Washington is home to the Seattle Basin, whose geometry and geological units amplify main and aftershock waves. Washington and California should first implement better building regulations, and if the premise is successful, it could be applied anywhere large magnitude earthquakes occur.
Hickory Estates is a community where buildings in the 1920’s through the 1940’s where build very quickly. This community has sloping streets, and is located above the Clearwater River. This area has single-family homes constructed with multistory, and wood-framed built homes. The population of this community is 6412 residents. Due to the era the homes were built in, a typical problem is the connection between the wood frame and the foundation. The lack of steel reinforcement can cause major damages due to its weak points0. An earthquake can cause the wood frame to come off its foundation, foundation cracks, the chimney breaking at the roof line, and the cripple walls (the walls between the top of the foundation and the floor diaphragm) to crack. This is why Hickory Estates has 8% of homes that will be uninhabitable after an Intensity IX earthquake.
A building or home can be seen as a place of comfort where individuals feel safe, relaxed, and at peace, but structures aren’t as safe as they really seem. Throughout time natural disasters as the name say’s just happen naturally without warning, and because of this, building codes exist to help prevent the worst when one occurs. However even with all these codes structures just aren’t safe enough to withstand disasters. Changing the simple things like building codes could greatly impact how much more reinforced a building can be in the wake of a disaster. Current structures are not up to code, and should be re-evaluated because buildings are vulnerable in the event of a natural disaster.
Critical incidents require immediate action (Levinson & Granot, 2002). Additionally, they also require ongoing support in order to ensure that they are correctly managed and the long-term effects are mitigated (Schneid & Collins, 2001). Addressed here are four specific events - earthquakes, floods, hurricanes, and tornados. There are ways to mitigate the damage of these events, and there are also ways to try to prepare for them. Additionally, the type of response to these events is important as is the recovery from them. For earthquakes, mitigation is limited. It is possible to build houses and buildings stronger and more able to withstand shaking, and in earthquake-prone areas the cabinets often have latches and large appliances are strapped to the wall (U.S., 2007). People who live there should also have emergency supplies of food and water, and should be prepared for an earthquake by knowing information about evacuation routes (U.S., 2007). The response to earthquakes and the recovery from them are usually strong, because the areas that are most prone are also most prepared. When an earthquake hits in an unusual area, however, it can take much longer to help people and to rebuild the infrastructure.
There are also things that we will do, if we suspect that there is a problem with the structure or the roof, which includes knowing the warning signs for failures. Things we will do before there is a threat of any type of weather, including, things to do after the weather issue. Before a weather storm hits, we will take certain measures to help limit building damage and safety issues. First, we will always have an emergency response plan in place before a weather event occurs, and we will make sure that everyone has easy access to the plan. Next, the maximum safe distance from the building's roof and the structure will be determined. The roof and structure will be regularly inspected for the structural integrity before a storm. After a storm the structure will be inspected, documented and repaired if needed. Furthermore, we will be proactive, and petition a local contractor with the proper credentials for structures, to go back behind the original construction crew to hold us accountable to the highest level. This ensures that in the event of a storm, a proper contractor and the paper work will be on
At Temple Square it seems like given the higher shaking risk and the high liquefaction potential, there would be some considerable damage to a number of buildings in that area depending on in the buildings there have been retrofitted.
On December 2nd around 10:30 a.m., a building in downtown Sioux Falls, South Dakota collapsed. Fear stuck the hearts of many as they heard the deafening collapse of a downtown building on 10th Street and Phillips Avenue. Many first responders and police quickly moved to try and find survivors. Hundreds of people waited for survivors to be pulled out from the debris. Cheers erupted when three hours after the collapse, firefighters found Emily Fodness alive underneath the rubble. Sadly, Ethan McMahon, a construction worker, was found dead underneath the rubble almost five and a half hours after Emily was rescued. Hultgren Construction is under investigation for causing the collapse.
If any architecture is structured poorly, erosion can easily contribute with destroying it. Architects have to design a building in a way that will be sturdy to complications like erosion.
On 9/22/17, the Phase II inspection was performed at the Naples Pier to evaluate the structural condition of the areas west of Bent 38. This report summarized the issues that were found for these areas, provided a possible explanation for the damages incurred given the information available, and discussed possible damage mitigation features that could help to preserve the pier from future hurricane induced damages. All repairs must be completed prior to reopening the Phase II area to the public. Damage mitigation features should be implemented at the same time as the repairs in order to save time and money.
Reckless endangerment is an illicit act that can result a substantial or serious physical harm to property or a person. This kind of behavior is punishable by law and can result in penalties ranging from a misdemeanor to felony which also carries mandatory jail time. An Engineer’s professional career should exemplify the core values of engineering competence, professionalism, accountability and honesty as the underlying “rule of conduct.” Consequently, all building designers shall make it their number one priority and responsibility to properly design and use quality parts to build all structures. The ASME codes of standards reiterate this fact with all the cannon outline as a guide to practice. “The fifty Nine Story Crisis” of the Citicorp

The Oral and Dental Hospital of Jenderal Soedirman University was built in 2008. This hospital’s building consists of 4 stories equipped with inpatient rooms, X-ray rooms, and laboratory. It is expected that with a main function as a public facility with a large number of people doing activities within it, the building has a high level of security when an earthquake occurred. The aim of this study is to perform a preliminary seismic hazard assessment, i.e. an evaluation using a Rapid Visual Screening method and a tier 1 evaluation using FEMA 310. The results of the Rapid Visual Screening were a final level 1 score compared with a cut-off score of +2.00. If the final level 1 score were less than or equal to +2.00, the building requires the tier
