What is the advantage of open-web floor trusses and engineered i-joists compared to dimensional lumber?
Trusses you can run all the ducts and piping in the truss, makes a much neater and easier to finish basement. Engineered beams are stronger and can span wider distances.
What distances do modern arch bridges typically span?
Modern arch bridges are held up by trusses. Typically these bridges span from two hundred feet up to eight hundred feet, or 4 meters. Arch bridges are smaller and span more narrow bodies of water.
How long is a suspension bridge?
There are many different lengths of suspension bridges.
How long are truss bridges?
the longest span of a truss bridge is 2.1 miles long
How can you submit a form without using a submit button in PHP?

Why do they build cantilever bridges?
because they cost only $1 million each and they are able to span long distances

Can roof trusses be built in half due to span?
There would have to be support under them where they meet.
The ability of a material to span horizontal distances with a minimum of support is called?
Tensile Strength -In architecture, the ability of a material to span horizontal distances with a minimum of support from underneath.
What are the strengths and weak nesses of a suspension bridge?
Suspension bridges are great for long distances and can span up too 7000 ft.! It s great for Long distances and its light weight. But its terrible under high winds . its very very flexible
How long to build span for bridge?
Tell us the size of the span, and what it is made from, and we may be able to get you an estimate. A single 6 foot board is 5 seconds, a 300 foot long concrete and steel span takes a little longer.
Why are trusses are so useful in structures?
With trusses you can obtain high strength of the bridge using rather thin and simple (i.e. cheap) elements. A drawback is that the required height of the side of the bridge rises with the span of the bridge, so trusses become less effective for larger spans compared to the cable bridges. Railway bridges have to sustain higher load than road bridges (trains are heavier), so trusses are an efficient design to increase strength.
what is recomended ratio depth-span for floor flat wood trusses?
I would just get it installed so you know it is done right but they have a graph to help you here http://www.raisedfloorliving.com/floorframing.shtml
How long does an arch bridge span?
My penis long
What is the attention span of a shrimp?
