How does a beam bridge support a load?
Beam bridges are the most simple of structural forms being supported by an abutment at each end of the bridge deck. No moments are transferred throughout the support hence their structural type is known as simply supported.
The simplest beam bridge could be a slab of stone, or a plank of wood laid across a stream. Bridges designed for modern infrastructure will usually be constructed of steel or reinforced concrete, or a combination of both. The concrete used can either be reinforced, prestressed or post-tensioned.
Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them. The main beams could be I-beams, trusses, or box girders. They could be half-through, or braced across the top to create athrough bridge.
A footbridge using beams over a stream in Dordogne, France
Because no moments are transferred, thrust, as from an arch bridge, cannot be accommodated, so leading to innovative designs, such as lenticular trusses & bow string arches, which contain the horizontalforces within the superstructure.
Beam bridges are not limited to a single span. Some viaducts such as the Feiyunjiang Bridge in Chinahave multiple simply supported spans supported by piers. This is opposed to viaducts using continuous spans over the piers.
Beam bridges are often only used for relatively short distances because, unlike truss bridges, they have no built in supports. The only supports are provided by piers.

A tunnel is an underground or underwater (or both) route for the transit of people and/or goods. The tunnel is surrounded by rock or other earthen materials, water or other things, and these all apply pressure on the structure of the tunnel. Sometimes these structures fail.
The failure of a tunnel can come as the result of poor engineering or construction. A "bad" design or the failure of the construction crews to follow a design can leave a tunnel vulnerable to failure. Additionally, there may be earthquakes or other natural disasters, fires or explosions in the tunnel, or other events that the tunnel was not made to withstand, and collapse is possible under the circumstances.

What is the name of the most famous arch bridge?
The Pont-Neuf (New Bridge) which is despite its name, the oldest bridge in Paris, and the Pont Alexandre III (opposite the Invalids) with its magnificent lamp posts are certainly among the most famous.
What are various design factors that influence energy saving in building construction?
I presume you mean that you want the completed building to save energy as opposed to the construction process. First and foremost is holding on to heat (or cold) that you're paying to create (you "pay" for firewood with your time, energy and the various costs associated with your chainsaw and splitting gear). Insulation and sealing inside against outside are the keys to this endeavor. Some of the most highly effective ways of pursuing these goals are "Earth Bermed/ Sod covered/ or Underground construction and the use of vestibules to prevent the wholesale loss of conditioned air when someone enters or leaves. Kind of like an "Air Lock" on a space shuttle (or an as-yet fictional Star Ship). For many folks, siting a house into a south facing slope is not practical. Other factors become more important (they're always important). There are limits to how much you should seal a house (especially in moist environments). Highly efficient appliances, though expensive, have usually paid for the cost difference somewhere from 3 to 10 times over the life of the appliance. In these days of greater energy costs, that number should be greater. Natural lighting can be a huge efficiency factor, as can be having properly calculated windows and overhangs on the East, South and West sides of your house. There are many good books on "Solarizing" your house plans. one I highly recommend (if you can find it is called "other Homes and Garbage" (a play on "Better Homes and Gardens" magazine title).
Why shear force and bending moment is zero in trusses?
An ideal truss has pin joint connections, allowing laod to be taken only in tension and not in bending or shear.
In reality, truss joints are not pinned, and do carry some moment and shear, but because tensile stiffness dominates, the moments and shears are small and called secondary.
What is the yearly average salary of civil engineers in South Africa?
A PrEng civil engineer can expect to earn between R500K-R1,5m per annum depending on experience and specialization. The EDM website www.edm.co.za also has a good salary survey.
What is the largest man made structure in the world?
In terms of volume and length it is the Great Wall of China (just over 5000 Km). In area, it is the low lying area of the Netherlands that have been reclaimed from the Sea (which means that the usable land is technically "man made"). By height, it is currently the Burj Dubai. In extension (length) it would be the internet.
Why are arch bridges better than than beam bridges?
Arch bridges are better because they transfer the weight down the archs and into the grownd unlike the beam bridge where it transfers it's weight through the beams wich break more often than arch bridges.

Importance of anthropometrics?
Anthropometrics literally means man (anthro) measurements (metric). It is the measurement of the size and proportions of the human body, as well as parameters such as reach and visual range capabilities. Anthropometrics enables us to properly size items, including system interfaces, to the "fit" the user.
How might a map of citys landforms help an official who is planning a new city park?
The map will show what areas would be best for a park.
Who used the Bering land bridge?
It is not who, but what. The land bridge was created by a lowering of the sea level when huge amounts of water was stored in ice caps, or glaciers. When the ice age ended, all of the water that was trapped inside was released back into the sea, and the land bridge was consumed.
