Civil and Structural
Everything in this wonderful world of ours just keeps getting bigger and bigger.  Civil and structural engineering helps shape todays world. Whether it's towering skyscrapers or bridges spanning unfathomable distances,  if it's newsworthy you'll no doubt see it here.

Could steal beams in the Twin Towers really have melted?

Clipped to the Drawing Board by Ryan  
The destruction reported regarding september 11 may not have actually occored.  There are many conspiracy theories surrounding this monumental event and this analysis may lend weight to some of them.  Considering this was the first time anything like this had happened before we don't really have much in the way of experience to draw upon.  As a result engineers turn to similar results in other areas as a comparison.  This guy reckons there's no way those steal beams could have melted due to the impact and explosion of the planes.

Millau Viaduct - tallest bridge in the world

Clipped to the Drawing Board by Ryan  
Engineers are always pushing the boundaries of what's possible.

Reaching taller than the Eiffel tower this is truly a marvel to be observed. A lot of information about it's construction and maintenance is available which is a rather interesting read. Indeed the structural statistics are just as fascinating,  as is the shadow that this monolithic structure casts.

Bendable Concrete Protects Against Hurricanes

Clipped to the Drawing Board by George Tan  

 New building codes and soaring insurance costs are triggering a drive by engineers to develop new materials and structures that are more resistant to hurricanes, as well as other natural calamities such as earthquakes.

21 Large Cities in danger from rising seas

Clipped to the Drawing Board by Ryan  
Well if you're a civil engineer the next few years may prove interesting for you.  Of the 33 cities predicted to have at least 8 million people by 2015, at least 21 are highly vulnerable , says the Worldwatch Institute.  While I doubt we're headed for something along the lines of 'WaterWorld',  this is still an alarming prospect and there will be some interesting challenges to overcome.

Wireless bridge sensors that power themselves

Clipped to the Drawing Board by Ryan  
Monitoring bridges is an important thing to be doing,  nobody would deny that.  Actually doing it though is a bit tougher.  We have the technology,  but up until now it hasn't been an easy task.  Installing the sensors is easy,  keeping them powered has been prohibitively costly. Up until now that is.  Researchers have developed a means by which to power these devices by converting the vibrations in the bridge caused by traffic into electricity to power the devices.  Which not only saves money on maintenance but is also environmentally friendly.

More accurate earth quake simulation

Clipped to the Drawing Board by Ryan  
A new kind of simulator at New York’s State University at Buffalo replicates the motion earthquakes induce inside buildings, where distance from the ground and building height can dramatically magnify ground movement in complex motions that differ from floor to floor.

Now they are able to go more in depth than the traditional shake tables and getting more accurate representations of how earthquakes can affect higher buildings.

Google maps can be a valuable tool

Clipped to the Drawing Board by Ryan  

While not strictly engineering as such,  I feel this article demonstrates a use of Google Maps that may be of use to many engineers. 

For many civil and structural engineers I imagine this would be a useful tool.  Possibly for people involved in plant layout as well.  While the minor details are always important,  being able to take a look at the grand scheme of things is also just as valuable.

How to build today's supertalls

Clipped to the Drawing Board by Adam Crighton  

Some people have always got their heads in the clouds and try to Reach for the sky - literally - go, go, go

A white hard-hat on his head, the earnest look of a professor on his face, Bill Baker has a ready metaphor to reveal the hidden structural logic behind Chicago's unprecedented reach into the sky.
