yes.\nbut is that all your Q?\n:)

Immigrant labor. Heh! Seriously though...\n\nVisionary architect, John Augustus Roebling designed five suspension bridge in his lifetime. Two, the Cincinnati-Covington Bridge (completed in 1867) and the Brooklyn Bridge (completed in 1883) are still standing today. The Brooklyn Bridge is considered Roebling's masterpiece.\n\nWork officially began on the Brooklyn Bridge in 1870. Roebling himself died of tetanus in 1869 from an injury sustained while working at the bridge site. His son Washington, also an accomplished engineer took over direction of the construction after his father’s death. Washington participated in continuous underground work in "caissons", huge airtight cylinders which enabled laborers to build the bridge's foundation. Washington unfortunately became crippled by the bends and was bedridden. Thanks in great part to Washington's wife, Emily, construction went forward. Emily quickly learned engineering to better oversee the builders and report back to bedridden Washington. In 1883 the Brooklyn Bridge, then known as the "Great East River Bridge," opened to the public. The final cost to build was a little over $15 million. Twenty-seven men overall died during construction.\n\nThe Brooklyn Bridge, now a National Historic Landmark, is Brooklyn's most beloved tourist attraction as well as the connection between Brooklyn and Manhattan for over 140,000 vehicles daily.\n\nThe bridge's main span over the East River is 1,595 feet (486 meters) and takes you from Manhattan's civic center into tree-lined Brooklyn Heights. The height of its twin, gothic-style arches above the water reaches 276.5 feet (84.3 meters).

If you simulate a geometrical structure in the form of an arch you will have the most evenly distributed stress.and the moment will be the same at all points.\nIf your question refers to how you tied a stell structure together ,the modern method is glue it to gether with a special glue designed for that purpose.

Well, you didn't say whether you're building a building, a bridge, a trestle, a tower, or other structure.  But you could start with some general articles, like this Wikipedia article, which has links to specific sites which give some specifications.\n\nThe other link gets properties for different I-beam sizes--I presume you understand the terminology well enough to read the resulting tables.

Here's a few websites, do your own homework!  :-)\n\nhttp://www.nature.nps.gov/nnl/\nhttp://www.cubekc.org/architivities/landmark.html

http://en.wikipedia.org/wiki/Civil_Works_Administration\n\nheres a webpage i found, i dont know whether it answers your question or not....but it explains about the administration...\n\nhttp://www.civilworks.com/\nhttp://www.usace.army.mil/civilworks/\n\nand here are some website, perhaps after go through the pages, you will have a brief idea about civil works\n\ni think its all about buildings and stuff...for the public usage, like building bridges, roads, etc....\n\ndoes that answer your question? i hope yes....

Try the ASCE research library it has some good articles on civil engineering.\nYou will have many options to choose for example you can choose bridges

If you have to actually build this thing then a castle-style drawbridge would probably be the easiest thing I can think of. \n\nBuild a tower out of boxes, wood or whatever. If you’re real lazy simply stand a shoebox on its end and paint an archway on what was the bottom.\n\nCut a piece of cardboard slightly narrower than the base of the box and about 8 inches long. That piece of cardboard is your span.  Bend the first couple of inches of the cardboard up at right angles. Push thumbtacks through that bent up section and into the tower a few inches above the tabletop. That way when the span is lowered it will slope downwards on to the table.\n\nPass a piece of wire through a cotton spool and bend both ends around to make a U shape. Bend the ends of the “U’ shape into tight circles. You can now put a screw through those circles and into a piece of light wood/heavy card that you can glue to the tower somewhere near the top.\n\nPoke a hole in the free end of the span. Tie some thread through it. Pass the thread around the cotton spool a few times. \n\nYippee, finished in one afternoon.\n\nWhen you turn the spool the span will lift. The spool is both a wheel and a pulley system. The span itself functions as a lever. Because the span slopes downwards onto the table top it is an inclined plane/ramp.\n\nAttaching a couple of parts using screws and a couple more using nails/tacks gives you your screw and wedge.\n\nSimple. Next time don't procrastinate.

It's called civil engineering design. Most of these things are designed by the engineer as needed, based on the size of what they are putting in. Sorry, but you probably won't find any cookie cutter designs floating on the internet. Some design companies may have them internally.
