Collapse Of I-35w In Minnesota Research Proposal

The epoxy supplier knew full well that his brand wasn't good for the long haul and assumed the construction bosses knew that too -- but they did not know that. So, the bottom line is that the I-35W bridge "apparently lacked the kind of redundancy planning that is the norm today," Teschler asserts. And since the I-35W bridge was designed in the 1960s it went online prior to the ASCE began noticing the "increased frequency of structural failures" -- an unfortunate bit of timing indeed.

Conclusion

The new I-35W bridge that spans the Mississippi River and provides a reliable route into and out of the Minneapolis area has been fitted with "a complex array of more than 300 sensors" which will hopefully act as a "structural health monitoring" system (Murray, 2008). Typically, Murray writes in Design News, sensors are applied to older structures; but in this case, taking extra care to assure the safety of the bridge...

...

It is too bad sensors weren't installed on the original bridge construction; lives may well have been saved.

Ethics Ethically, the Red Cross strives to be politically neutral in most of its efforts -- the American Red Cross stresses personal readiness and preparedness on its website, rather than takes a position on anti-terrorist operations, for example, or bridge inspection. For the International Red Cross, political neutrality is of particular concern, as to safely travel in unsafe areas and solicit donations from multiple sources, the organization cannot appear to be

Tornadoes: Nature's Phenomenon What is a Tornado? A tornado is "a violent, destructive, whirling wind accompanied by a funnel-shaped cloud that progresses in a narrow path over the land" (Merriam-Webster, Incorporated, 2012).

A tornado can have the strongest winds on

In homes and buildings, the thermal mass of concrete plays a big role in energy efficiency. The high thermal mass of concrete offers this benefit: it stores and releases the energy required for heating or cooling and hence, reduces "temperature swings in homes and buildings." Interestingly, concrete also helps big rig trucks and "over-the-road trucks" use less fuel; that is because concrete's rigid pavement design is better than asphalt pavement

Bridge Design and Engineering Bridges are an integral but often overlooked part of today's commuting society. Most drivers feel completely secure and grounded when on any well-designed bridge, even though they may in fact be hundreds of feet in the air above a large gap or body of water. Bridges are not only functional for travel, but may be the key to growth and survival of many areas that would otherwise
