RUBBER TYRED METRO RUBBER TYRED METRO

  • A Rubber-tyred metro is a form of rapid transit system that uses a mix of road and rail technology.
  • In this the vehicles have wheels with rubber tyres like a bus, but using a set of two parallel concrete or corrugated steel rollways, each with the width of a tyre.
  • The vehicles have wheels with rubber tyres which run inside a guide way for traction, as well as traditional railway steel wheels with flanges on steel tracks for guidance.

Urban planning

Urban planning is a mixture of science and art. It encompasses many different disciplines and brings them all under a single umbrella. The simplest definition of urban planning is that it is the organization of all elements of a town or other urban environment. However, when one thinks about all the elements that make up a town, urban planning suddenly seems complicated - and it is.
Real urban planning is a relatively new concept. It gained popularity beginning in the mid-to-late 19th century, when it became obvious that there should be some kind of plan or larger goals for the growth of big cities like New York and Philadelphia. Before this time, cities very often grew as they had need, and the surrounding land was just swallowed up. London, Paris, Tokyo - none of these world cities had much urban planning, and even now, the addresses and streets in their older sections can be confusing even to natives.
Urban planning also became popular because of the growing need to get factory workers into healthier housing, rather than stuffing them into fire-trap tenements. With the advent of unions, workers had advocates to help lobby for better housing. Hence, “mill villages” and “steel villages” sprang up in larger cities.
Nowadays, urban planning takes all aspects of a city into consideration. It includes plans for safety, aesthetics and common sense placement of everything from houses to factories. Parents wouldn’t want their children’s playground next to the water treatment plant, for instance, and urban planning helps eliminate such problems. Goals for attractive architecture for city buildings are put into place and pleasing green spaces are planned. Good urban planning gets schools into the neighborhoods where they are needed most, places hospitals in centralized locations, allows for growth and plans highways accordingly.
Perhaps good urban planning is most evident in good highway planning in a city. Anticipating growth and traffic needs for a big city is crucial. Urban planners must consider how future growth will affect traffic flow and try to eliminate trouble spots before they become a problem. Even placing sewer systems and drainage systems is a necessary element of urban planning, albeit a less glamorous one. Urban planners must consider geography, the water table and numerous other elements of a city’s landscape in order to properly plan for this necessity.
Because so many disciplines make up the larger concept of urban planning, a group of urban planners may have widely divergent degrees: civil engineering, architecture, botany, landscape design, electrical engineering, business administration, and so on. Urban planners who are good at what they do are highly sought after by municipal governments. When efficient urban planning is used, cities are more attractive and serve their citizens to the best of their potential.

LOAD BEARING MASONRY

Load bearing masonry is among the oldest and most widespread building techniques in the world. The earliest load bearing masonry consisted to stones stacked one over the other. Over the passage of time, the stones were chiseled and dressed to make more stable masonry walls. The firing of earth blocks gave rise to the earliest form of brick masonry. Over the centuries, masonry has evolved into a precise science with a myriad of options in materials and styles. Some of the more common load bearing masonry used today is brick, stone and concrete masonry units (CMU) or concrete blocks. Among these there are several varieties depending on the materials and system of laying the masonry units. Some of the more recent advancements are aerated concrete blocks, hollow concrete blocks, autoclaved ceramic blocks etc.
Masonry can be classified in the following manner:
  • Material: Stone, brick, block
  • Cavity or non cavity
  • Reinforced or non-reinforced
  • Composition: one material or composite
load bearing masonry construction
Masonry typically involves the laying the masonry unit (MU) one layer at a time. A mortar is used to hold the MUs in place and provide them with strength and stability. Mortars can be of several types but the broad classification would be cement mortars, lime mortars and synthetic adhesives. Earth is also used as mortar in some parts of the world.
Load bearing masonry by its nature, is a time consuming construction technique. Laying brick after brick, course upon course is a tedious process. The advent of panelized systems, load bearing masonry began to lose favor with home builders in the industrialized world. Advancements such as quick setting mortars have helped quicken the process. Attempts to mechanize the masonry process by using brick laying robots have met with limited success and skilled masons remain valued the world over. Another attempt at speeding up the masonry process has been through the use of mortarless masonry or dry masonry. This type of masonry uses factory made interlocking blocks that can be laid without the use of mortar.
There has been a recent resurgence in the use of load bearing masonry as more and more users have begun to recognize its advantages. Masonry is seen as a symbol of permanence and solidity. It is highly fire resistant and has a high compressive strength. In addition to this the appearance and texture of masonry is preferred by many and the innumerable patterns possible in masonry make it a popular construction technique.
The advantages of using load bearing masonry are:
  • Load bearing masonry is solid and durable.
  • It is fire resistant.
  • There are several colors and textures available.
  • The tools and implements used are simple and low-tech.
  • Does not require a great deal of preparation or fabrication in advance.
  • Load bearing masonry has high compressive strength.
  • Aesthetically attractive.
The disadvantages of load bearing masonry are:
  • A slow and tedious process.
  • Requires skilled masons.
  • Cost of bricks can make it unviable.
  • Low tensile strength, can fail during earthquakes.
  • Load bearing masonry, especially brick masonry is porous and needs to be protected from water.
  • Load bearing masonry has a high self weight.
  • It has poor thermal insulation properties.
The problem of high heat conductance can be reduced in the following ways:
  • By providing air traps – double walls and rat trap bonds.
  • Using insulation in the form of Exterior Insulation and Finish System (EIFS)
  • Interior insulation such as batt insulation and stud walls.
  • In-wall insulation made of polystyrene, vermiculite etc.
Building codes for load bearing masonry are well established and well documented. In the United States, the engineering design of masonry is governed by the American Concrete Institute and the American Society of Civil Engineers. All aspects of masonry are clearly listed and described. The code mandates that the thickness must be at least 6 inches in case of single story buildings and at least 8 inches for structures more than one story.

COMPACTION OF SOIL PROCTOR’S TEST

TO DETERMINE THE COMPACTION CHARACTERISTICS OF A SOIL SPECIMEN BY PROCTOR’S TEST
Theory:
Compaction is the process of densification of soil by reducing air voids. The degree of compaction of a given soil is measured in terms of its dry density. The dry density is maximum at the optimum water content. A curve is drawn between the water content and the dry density to obtain the maximum dry density and the optimum water content.
Dry densityclip_image001

Where M = total mass of the soil, V= volume of soil, w= water content.
Equipment:
1. Compaction mould, capacity 1000ml.
2. Rammer, mass 2.6 kg.
3. Detachable base plate.
4. Collar, 60mm high.
5. IS sieve, 4.75 mm.
6. Oven
7. Desiccator
8. Weighing balance, accuracy 1g.
9. Large mixing pan
10. Straight edge.
11. Spatula
12. Graduated jar
13. Mixing tools, spoons, trowels, etc.
Procedure:
1. Take about 20kg of air-dried soil. Sieve it through 20mm and 4.7mm sieve.
2. Calculate the percentage retained on 20mm sieve and 4.75mm sieve, and the percentage passing 4.75mm sieve.
3. If the percentage retained on 4.75mm sieve is greater than 20, use the large mould of 150mm diameter. If it is less than 20%, the standard mould of 100mm diameter can be used. The following procedure is for the standard mould.
4. Mix the soil retained on 4.75mm sieve and that passing 4.75mm sieve in proportions determined in step (2) to obtain about 16 to 18 kg of soil specimen.
5. Clean and dry the mould and the base plate. Grease them lightly.
6. Weigh the mould with the base plate to the nearest 1 gram.
7. Take about 16 – 18 kg of soil specimen. Add water to it to bring the water content to about 4% if the soil is sandy and to about 8% if the soil is clayey.
8. Keep the soil in an air-tight container for about 18 to 20 hours for maturing. Mix the soil thoroughly. Divide the processed soil into 6 to 8 parts.
9. Attach the collar to the mould. Place the mould on a solid base.
10. Take about 2.5kg of the processed soil, and hence place it in the mould in 3 equal layers. Take about one-third the quantity first, and compact it by giving 25 blows of the rammer. The blows should be uniformly distributed over the surface of each layer.
The top surface of the first layer be scratched with spatula before placing the second layer. The second layer should also be compacted by 25 blows of rammer. Likewise, place the third layer and compact it.
The amount of the soil used should be just sufficient to fill the mould ad leaving about 5 mm above the top of the mould to be struck off when the collar is removed.
11. Remove the collar and trim off the excess soil projecting above the mould using a straight edge.
12. Clean the base plate and the mould from outside. Weigh it to the nearest gram.
13. Remove the soil from the mould. The soil may also be ejected out.
14. Take the soil samples for the water content determination from the top, middle and bottom portions. Determine the water content.
15. Add about 3% of the water to a fresh portion of the processed soil, and repeat the steps 10 to 14.

The Tallest Buildings in the World

When speaking of the tallest buildings in the world, it is important to specify exactly what is being measured. Listers must decide if the building is to be measured from sidewalk level or below, whether or not TV towers or masts are included, and whether an antenna, flagpole, or spire should count. A building is considered to differ from a tower in its primary use, being designed for residential, business, manufacturing, or mixed use, whereas a tower is not.
The Council on Tall Buildings and Urban Habitat, formerly the Joint Committee on Tall Buildings in conjunction with Emporis Buildings, is the authoritative source for information about the tallest buildings in the world, and their list of the tallest buildings, drawn from an extensive database, is based on the height of the building to the structural or architectural top, which includes spires and pinnacles, but does not include antennas, masts, or flagpoles. Prior to 9/11, the twin towers of the World Trade Center in New York City, New York were ranked fifth - 1,368 ft (417 m) – and sixth – 1,362 ft (415 m) – on the list of the tallest buildings in the world.
Interesting facts:
  • The tallest building in the world, Taipei 101, is nearly 200 feet (61 m) taller than the next tallest building.
  • Of the top ten tallest buildings in the world, all are either in Asia or the United States.
  • Of the top 20 tallest buildings in the world, the most, five, are in China, with four in Hong Kong, three in Chicago, and two each in Taiwan and Kuala Lumpur.
  • In the top 100 tallest buildings in the world, the only ones completed prior to 1969 are all in New York City and were completed between 1930 and 1932. They are: the Trump Building, originally called the Bank of Manhattan Trust Building, and the Chrysler Building – 1930; the Empire State Building – 1931; and the American International – 1932.
  • In the top 200 tallest buildings in the world there are:
    • 25 in New York City
    • 17 in Hong Kong
    • 13 in Shanghai
    • 12 in Chicago.
    • 8 in Dubai
    • 7 in Singapore
    • 6 each in Tokyo, Seoul, Sydney and Houston
    • 5 in Kuala Lumpur and Shenzhen, China
    • 4 each in Los Angeles and Melbourne and Toronto and Atlanta
