Building Advantages And Disadvantages

The development of multi-story buildings has followed the growth of the countries. These countries have a highly increasing population and migration, so they need a high rise building for different function such as; residential and commercial. Nowadays, the high rise buildings demonstrate the strength of the economy of the country, so modern buildings have become taller, stronger and more attractive than that were in the past. This is depends on mechanical equipment likes elevators and water pumps .Also, the programs that made an easy to design a high rise buildings. Moreover, the construction material that use in built such as; steel or reinforced concrete frameworks and glass curtain walls.

An example of modern building in the UAE, with multi

Aggregates which are mixed of fine to coarse that help to increase the strength of concrete. Hydration process occurs when cement mixed with water and that caused hardness for the cement. Moreover, there are an advantages and disadvantages of concrete. On one hand, some of the advantages of concrete are economical, high durability

and resistant to wind, water, rodents and insect. On the other hand, the concrete has some disadvantages which are low tensile strength, low ductility and susceptible to cracking.

2.3.2 Steel:

Steel is used in many forms of construction and it is present in nearly every form of reinforced concrete. Structural steel is composed mainly of iron with a small amount of carbon (>2%). Carbon has a very marked effect on the properties of steel that increased the hardness. Moreover, steel has many properties that is needed to be considered by designers such as strength, toughness, ductility and durability. Toughness is the ability of a material to absorb energy and plastically deform without fracturing while ductility is a measure of the degree to which a material can strain or elongate without fracture. Whereas, durability is long lasting material that resists wear. In contrast, steel has disadvantages which are

Nowadays most of people work in the center of the city and also there is another problem, city attractions for tourists are in the center of city. Therefore, the multi-story buildings decrease the energy of transportation to reach several terminuses in the center of the city and this can be very helpful to the environmental. However, concentration of population in one area causes problems in traffic or in availability of parking lots, which considered a big problem in our country, especially in Abu Dhabi and Dubai. The parking problems can be solved by constructing basement level for parking lots which should be sufficient to provide adequate space for all vehicles of residents who lives in those multi-story building.

2.6.2 Potential Ethical Issues:

After what we have discussed in last paragraph there are some disadvantages that caused by increasing the number of multi-story buildings. The important reason is that it might affect the identity of the country. For example, there are some old houses and archeological
