The fancy term in the heading simply translates to a reference to any structural system that has a distribution of load from the various surfaces in such a way that the outermost skin bears the load. In terms of it being a term used in architecture, the outermost skin of the building or the facade of the building bears the load of the superstructure unlike a regular post and beam construction.
An ‘Egg’ is probably one of the best examples via which this structural phenomena can be explained: the skin bears the load of the inner contents while providing a certain degree of rigidity, protecting it from the external agents of stress. Inspiration from such a system has led to the implementation and construction of designs of iconic buildings like the Capital Gate (Abu Dhabi), the HSBC Towers (Shanghai), the Lloyds of London and so forth.
The next time you devour your breakfast consisting of scrambled eggs, please make sure you try and observe the detail around you because inspiration is anywhere and everywhere, all one needs to do is LOOK!
