Civil Engineering

An influence line is used to show the effect of a dead load. This data normally manifests in a graphical display. Dead loads are permanently on the structure. The weight of the structure, or other similar elements is called a dead load.

The frost depth level below area's usually not less than 800 mm .

The relationship is interference is the addition of two or more wave pattern and the principle of superposition is the displacement of any point due to the superposition of wave system equal to the sum of the displacements of the individual waves at that point.

the yield strength of EN8 material is 465MPa.

you can generally use 180 degree hooks, to provide enough anchorage in slabs with no edge beams. use the Ldh formula (12.5.2) of ACI 318-11

There is no standard. Each college and university has a start date particular to itself. However, the approximate start date for most institutions within the United States is around mid January. The college I teach at starts January 22, 2009.

Tolls provide money for the government.

Bridge's also provide a passageway for transportations including automobiles, ferries, ships, and trains.

Efficient means of transportation vs taking a ship to the desired location.

Links to area's together.

Transportation time is much faster, and price of a toll is much less then a boat ticket.

IPS - Indian Patent Stone flooring is called IPS flooring which ordinary screeding concrete with vacuum dewatered finishing for industrial floorings. This is used for doing epoxy flooring purposes.

Bridges are very complex structures that must be carefully engineered using long-lasting and strong materials. Some of the materials that are used for bridge building includes stones, cement, steel, wood, and composites.

I assume that you want the longest.

This is the Bang Na Expressway and it goes over land. It is not always on the list of bridges because it does not cross water. It has two tolls booths on it and covers 33.5 miles

The longest bridge over water is over Lake Pontchartrain. This causeway was a surprise to me when I first crossed it. I was almost out of fuel when I entered the bridge the first time. I learn quickly though! It covers roughly 24 miles. Not a great feeling on empty! (I made it!)


The largest suspension bridge is Akashi-Kaikyō Bridge in Japan. It crosses the strait of Akashi.

Hmm lets see. Volume of cylinder * denisty of steel. I hope you want metric.

1. convert mm to m for ease of use. 16 mm = 0.016 m

2. length equals 1 m

3. density of steel varies a little but 7850 kg/m3 should be good

4. volume equals PI*R^2*L = 3.14*0.008m^2*1= 0.00020096 m3

5. weight equals density * volume = 0.00020096 * 7850 = 1.577536 kg/m

The amount of steel required in concrete as reinforcement is measured using a formula that calculates the amount of pressure that will be put on the concrete. There are different formulas to identify the minimum and the maximum amount of needed steel, depending on if you are making a beam, slab, or column.

The tallest man-made structure in the world is The Burj Dubai in the Dubai, United Arab Emirates. It is still under contruction, but when finished, it will be 2,684 ft. tall. But the tallest man-made strucute that is completely finished is the Taipei 101. It is 1,671 feet in height.

Since you're already using concrete, not much point in using the lighter, weaker, and more expensive aluminium. And lead is really weak, environmentally hazardous and more expensive than iron.

• It involves a configuration the combines strength and productivity. The designing uses SAE steel grades (essentially an amalgamation of carbon and alloy steels) which renders the framework strong yet complex. It ensures that any beam, strut or tie ends only undergo tensional or compressional forces.
  

it's fairly simple. The shear strength of the material must be known. Steel is normally 44000 psi in single shear and 88000 psi in double shear. The cross-sectional area of the nail times the shear strength will give you the point of failure of the nail itself, or maximum destructive load. s x a = l

Example: an 8d common nail has a diameter of 0.131 inches and a shear strength of 45000 psi the destructive load capacity of the nail in single shear is:

45000 psi x (0.131" x 0.131" x 0.78539) = 606.513 pounds of force. Divide this number by the required factor of safety to get the maximum design capacity for your structure. [ often f.s. = 3, 4, or 5]

* cross-sectional area = diameter squared times 1/4 pi

note: shear strengths of nails often exceed the crush strength of the material in which they are used.

It depends on the weight of the bag.

To calculate the volume of any bag we need to know the density. In freshly packed bags the standard density is 94 lbs/ft3 (1505 kg/m3).

Example: to know the volume of a 50kg cement bag we divide the bag weight by the density, i.e.:

50 kg ÷ 1505 kg/m3 = 0.0332 m3

In practise, sand, cement and gravel are sold by weight, yet they must be mixed by volume. the black rubber buckets used in the building trade hold one 25kg bag of cement. a standard builders wheelbarrows volume is 70Lts so holds 4 of these buckets. The standard shovel here in Ireland is the long handled dovetail and 4 heaped shovels fills a bucket as near as need be.

They are the one who sends data to the processor...

The north bridge also the who controls video card,expansion cards or graphics cards and south bridge controls the drives and onboard devices.

In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.

If we use a light weighted material offered no resistance then the beam deflects as per the diagram.

Depends on where it is. If it is the center wall that runs down the middle of the house under the peak of the roof, then yes. Usually the ceiling joist are lapped on top of this wall. Any outside wall is also. cross wall around upstair bath may be also. Almost any wall can me moved and a beam put in it's place but you need to know what you are doing to do it. Broad, general rule of thumb is any wall running the same direction as the main peak of the roof probably is a bearing wall.

Depends on what alloy you mean. If you are talking about pure Al (AISI1xxx), it is generally accepted to yield about 7-11Mpa.

Another thing to consider is that Al does not have as pronounced yield as say Fe systems. The 0.2% offset stress is used in most calculations regarding Al yield stress and is calculated as follows:

L = length of sample

->0.2%*L=0.2% offset strain.

Plot this point on stress/strain graph and draw line from this point on the strain axis parallel to the elastic slope of the material until it reaches the data points. This intersection is the 0.2% offset stress point.
