  1. because it doesn't have arms to put the strap inside the belt so it ends up falling off!!!

    HAHAHAHA

    IM SOOOOO GOOD!!!!!


  2. Basically the concrete or steel frame is sufficiently proportioned to carry the vertical weight of the building and any lateral loads from wind or earthquakes.

    Regarding Anthony B's comments about the structural limit of concrete - we are far from it! The glass on large buildings is non-structural, in that they carry the loads directly applied to it, i.e. self weight and wind loads, but they are suspended from the floor structure above, whether steel or concrete frames.

  3. The structure is designed to transfer the weight into the ground.

  4. Foundations!

  5. Because the vertical columns are braced by the floors and internal cross-members in the walls, so that the maximum unbraced length in compression is relatively short. As a result, the Euler crippling load for each strut section is higher than the weight being carried.

  6. It`s the job of the architect to design the building of such a strength that it will withstand it`s own weight plus other external forces, such as side winds.

  7. A lot of older buildings used buttresses. These were there to shore up the walls, and transfer the weight of the roof into the foundations.

    It is interesting to note, that during the construction of StPauls Cathedral, the masons refused to work on the dome - believing it would colapse during construction. - They were only standing on timber scaffolding at the time. It's still there.

  8. Traditional skyscrapers are built with reinforced concrete with infused steel rods. The concrete is good at being compacted, but not stretched, the steel is vise-versa.

    Modern skyscrapers use a lot of glass for support. This specially treated glass can withstand severe shocks, up to one ton of weight.

    The main reason it has changed to glass it because we are reaching the structural limit of building with concrete.

  9. because the weight is perfectly balanced and is spread evenly across the bottom also there built well lol

  10. Proper engineering prevents it.

  11. A structural engineer can refer to the maximal loading properties of the materials the architect intends to use, and approve them if they will stand the stress placed on them...  I'm aware that a steel skyscaper can be built over eight times higher than the tallest brick building can, as the lowest bricks would be crushed by the weight acting on them at a certain limit.

  12. The center of gravity on these types of tall buildings is usually below the earth's surface, preventing it form falling over.  In simple terms, there is a lot of support structure deep underground and that is why tall buildings don't collapse easily.

  13. hard bottom...

  14. they are built on pyles   I think that's the spelling ! but they go down several feet under the foundations,,,then the foundations and building is built on them,,,,they are like big girders,,,!
