General help with homework..?

Question

1) what materials are commonly used in the building construction industry?

2) what is the basic structure of the average skyscraper?

3) what are themost important characteristics of materials used to construct sky scrapers giving exact details such as the melting point and so forth

Answer 1

1) concrete, steel, glazing, metal, tiling, painting, joinery& ironmongery, electrical items, mechanical items ( plumbing, sanitary, HVAC, and others ), partitioning, Aluminum,.

2) Basic structure of the skyscrapers are the concrete and steel structure, and curtain walls in addition to all finishing materials and MEP.

3) The most members of the skyscraper have to be designed to withstand the fire beyond the melting point, either by adding protective coatings or incase the members with fire resistance materials

Answer 2

Here's a few ideas...

1) Concrete, Steel, Glass, Bricks and Mortar. In smaller buildings wood is often used for beams/flooring. In brick buildings wood is often used for lintels (beams which bridge a narrow gaps providing support for the walls above it) above internal door openings, although metal I-beams are becoming more common. External lintels are usually "weather proof" materials like stone, or concrete.

Fair bit of plaster board too, but that's for ascetics.

2) [Not 100% sure what this part is wanting]. Generally you've got a frame that's made up of pillars and beams (forming a box like skeleton). Each piller/beam is generally reinforced or pre-stressed concrete. Sometimes there's slabs that "slot together" (although MUCH less common since the Ronan Point collapse)

3) Temperature at which material starts to break down/burn..

Thermal expansion, can put strain on joins/beams, and differention thermal expansion can crack reinforced concrete. Most metals have a lower yeild point at elevated temperature.
