The primary important role of structural system for tall Buildings is to resist lateral loads.
Dead-end and other poles that support lateral loads have guy-wires to support them.
There are two forms of internal stresses caused by lateral loads:
Multiple components within the lateral load resisting system were found to be insufficient:
This involved the integration of a reinforced concrete core wall, to resist lateral loads, with a light steel floor framing.
The total frame behaves as a cantilever beam when subjected to lateral loads.
This arrangement is stronger than straight wheels and can accept higher lateral loads.
Steel diagonal brace frames extend from the ground to the roof to support the lateral load.
"Put a lateral load on the top and it will break."
It covers the case for small deflections of a beam which is subjected to lateral loads only.
