How is a bridge protected from a thermal expansion?
Bridges are fixed solidly to the ground at each end and sometimes at intermediate points. The road bed will expand and contract with temperature changes and if there is no provision for this to happen, the road bed can distort or break as the length changes. The same is the case for many elevated structures that have rigid fixings. A common technique to avoid damage is to make a break in the bridge deck. The break has a small gap or flexible insert between the two parts of the bridge deck and as the deck expands and contracts, so the gap changes size. This method means that a minimal force is exerted on the bridge supports and therefore structural damage is avoided. The longer the bridge, the more expansion can take place and several expansion gaps can be used. Typically, the gaps will allow for movement of less than one inch up to as much as twleve inches. Although the principle of expansion joints is very simple, the parts used are precision engineered to allow movement while retaining strength in the deck.
In l4d2 what happens if you stay on the bridge to long?
If you stay on the bridge nothing will happen unless you are playing online where your other teammates will leave on the helicopter without you
When did Bridge-It happen?
Bridge-It happened in 1984.
Can dogs walking across bridges make them collapse?
The likelihood of a dog walking across a bridge causing it to collapse is extremely low. Bridges are designed and built to withstand much heavier loads than the weight of a single dog. Factors such as the bridge's structural integrity, design, materials used, and maintenance are far more significant in determining its safety. It would take a highly unusual set of circumstances for a dog to cause a bridge to collapse just by walking across it.
Why are there gaps at regular spots in the side walk?
They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.
