What is deck slab?

Basically the Deck slab is the part of structures which is constructed over the girders and being used by the vehicles to cross over the bridge. It also acts as a medium to bind the girders, as the load of vehicles is directly taken by the deck slab and further transfered to the girders.

What is a road deck?

A deck is the surface of a bridge. A structural element of its superstructure, it may be constructed of concrete, steel, open grating, or wood. Sometimes the deck is covered a railroad bed and track, asphalt concrete, or other form of pavement for ease of vehicle crossing.

What is Q deck?

What is Q deck? “Q deck” was the common name for the HH Robertson Company's “Q-Lock Floor” composite floor deck, which was produced in 2” and 3” depths. The modern equivalents of 2”-QL-99 and 3”-QL-99 are 2” deep composite floor decks and 3” deep composite floor decks.

What is composite deck slab?

Composite slabs consist of profiled steel decking with an in-situ reinforced concrete topping. The decking not only acts as permanent formwork to the concrete, but also provides sufficient shear bond with the concrete so that, when the concrete has gained strength, the two materials act together compositely.

What does steel decking weigh?

Steeldeck® platforms have a very good strength to weight ratio. A 4' x 8' Steeldeck® platform weighs approximately 150 lbs and supports an evenly distributed load of more than 4,000 lbs.

What is metal decking used for?

Metal decking is used for flooring and roofing and also for the creation of forms for concrete. Metal decking is installed by using screws or pneumatically driven pins and can also be welded.

How far can metal decking span?

If you choose the latter, you'll have a little less steel because you have fewer joists to install, but you're replacing all those joists with heavier decking. reach spans of 30 ft.

What is corrugated decking?

Corrugated Metal Floor Deck Options Corrugated metal is a lightweight building material that provides remarkable rigidity given its slim profile. That strength makes it an ideal addition to concrete floors in need of extra reinforcement.

How much does metal decking cost?

One of the biggest factors that affects the price of a metal deck is the cost of steel. As with most commodities, the cost of steel fluctuates. In general, the prices will fall between $3.00 - $6.00 per square foot.

What is a composite beam?

Composite beam. A structural member composed of two or more dissimilar materials joined together to act as a unit. An example in civil structures is the steel-concrete composite beam in which a steel wide-flange shape (I or W shape) is attached to a concrete floor slab (see illustration).

What is the purpose of a sleeper slab?

A SLEEPER SLAB is a reinforced concrete block supporting the end of the concrete approach slab at the approach roadway end. It is typically used when preformed elastomeric compression joint seals are not used between the concrete pavement sections.

Why approach slab is provided?

Approach slabs serve to reduce the step which can result from settlement of approach embankments caused by consolidation of embankment fills and the underlying material. The smooth transition provided by approach slabs reduces dynamic vehicle loads on bridges.

What is bridge approach?

Bridge approaches typically experience two types of settlement, global and local. The purpose of the bridge approach slab is to significantly reduce local settlement and to accommodate global settlement by providing a gradual transition between the roadway and the bridge deck.

What is a transition slab?

Transition slab between the abutment and the deck of a bridge with expansion and contraction joints having a long service life, and methods for absorbing the expansion and contraction movements of the deck of a bridge.

What is abutment in bridge?

In engineering, abutment refers to the substructure at the ends of a bridge span or dam whereon the structure's superstructure rests or contacts. The term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.

How many types of slabs are there?

There are four different types of concrete Flat Slabs:- Slab without drop and column without column head(capital). Slab with drop and column without column head. Slab without drop and column with column head. Slab with drop and column with column head.

Why chlorophyll is important in photosynthesis?

The role of chlorophyll in photosynthesis is vital. Chlorophyll , which resides in the chloroplasts of plants, is the green pigment that is necessary in order for plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose. Simply so, why is chlorophyll necessary for photosynthesis? The sunlight absorbed by the chlorophyll serves as a catalyst. he importance of chlorophyll for photosynthesis is that it captures light energy from the sun to produce glucose via a chemical reaction. Chlorophyll specifically absorbs light from the red and blue parts of the light spectrum, and reflects green light. Secondly, why do plants have chlorophyll? Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. Hereof, what is the role of chlorophyll in makin...

What are two organelles that contain DNA and have a double membrane?

Mitochondria are large organelles containing DNA and surrounded by a double membrane. The inner membrane is highly convoluted, with deep folds called cristae . The membranes divide the mitochondrion into two compartments, the central matrix, and the intermembrane space. Also question is, which organelles have a double membrane and their own DNA? Mitochondria and chloroplasts , which have double-membranes and their own DNA, are believed to have originated from incompletely consumed or invading prokaryotic organisms, which were adopted as a part of the invaded cell. Likewise, what 2 parts of the cell have a double membrane? Double Membrane bound Organelles : Mitochondria , Chloroplasts , Endoplasmic Reticulum, Golgi Body, and Nucleus. Also question is, what are the two organelles that contain DNA? The three organelles that contain DNA are the nucleus, mitochondria and chloroplasts . Organelles are membrane-bound subunits within a cell -- analogous to organs in the body -- that p...

What is the actual focal spot in radiology?

Focal spot is the area of the anode surface which receives the beam of electrons from the cathode. It is the apparent source of x-rays . Subsequently, one may also ask, what is the actual focal spot? a circumscribed area or place, usually distinguished by its color; see also macula and tache. actual focal spot the section of a focal spot on which there is intersection of an electron beam with an anode of an x-ray tube. where is the focal spot on ax ray tube? The radiation is produced in a very small area on the surface of the anode known as the focal spot . The dimensions of the focal spot are determined by the dimensions of the electron beam arriving from the cathode. In most x- ray tubes , the focal spot is approximately rectangular. Also question is, what is the difference between actual focal spot and effective focal spot? Refers to the focal spot size when measured directly under the anode target. The actual is measured on the target itself. Actual Focal Spot does N...
