Timeline of three tallest structures in the world
Encyclopedia
This is the timeline of the 3 highest man-made structures in the world that have the strength to carry more than their own weight.
When several structures of the same height exists, the oldest is counted as the highest.
The second and third positions are not always definite. Older dates and heights have less evidence backing them. Dates when the Egyptian pyramids
eroded to their present height are uncertain, as are their original heights.
Land structures are measured from the ground level up (no basements). Off-shore platforms are measured from the sea floor up (the part buried below the sea floor does not count). Only off-shore items constructed in such a way that they would still stand without the support of ocean water are taken into account.
The 1500-metre-tall Magnolia ETLP is excluded from the timeline because this offshore tension-leg oil platform
is supported by the water, it is floating, and if the water were removed, the tension in its legs would most certainly cause it to buckle

Overview
A structure must have been still standing to be considered for that year. Only the height that the structure actually had that particular year is considered for that year, regardless of later modifications. At the points when old structures probably fell, new structures with more certain figures replace them.When several structures of the same height exists, the oldest is counted as the highest.
The second and third positions are not always definite. Older dates and heights have less evidence backing them. Dates when the Egyptian pyramids
Egyptian pyramids
The Egyptian pyramids are ancient pyramid-shaped masonry structures located in Egypt.There are 138 pyramids discovered in Egypt as of 2008. Most were built as tombs for the country's Pharaohs and their consorts during the Old and Middle Kingdom periods.The earliest known Egyptian pyramids are found...

Tension-leg platform
A Tension-leg platform or Extended Tension Leg Platform is a vertically moored floating structure normally used for the offshore production of oil or gas, and is particularly suited for water depths greater than 300 metres and less than 1500 meters...

Buckling
In science, buckling is a mathematical instability, leading to a failure mode.Theoretically, buckling is caused by a bifurcation in the solution to the equations of static equilibrium...
