01_FRAME SYSTEMS BY ANABEL OTERO
Architect: Foster and partners
The idea behind the building was expressing the nature of banking in the city in a built form, but involving feng shui geomancer.
The office building, due to the short time to finish the building process, most of the elements are prefabricated, including factory-finished modules. During the construction process, it was needed to build both upwards and downwards at the same time, therefore, they adopted a suspended structure, with pairs of steel masts arranged in 3 ways.
The final result was a building formed by 3 individual towers of different heights-29, 36, 44 storeys- This stepped configuration, created different floor plans that allowed the existence of garden terraces.
The use of masts was also very important because allowed moving the service cores to the perimeter to create a deep-pan floor and a public plaza on the ground floor completly open.
The 'bridges' that span between the masts define double-height reception areas that break down the scale of the building both visually and socially.
The type of structure is what is called the megaframe structure which is very typical from high rise buildings.
It also has a frame grid for the beams and structure
The masts, are arranged in 2 rows of 4 masts and are composed by steel columns. The groups of this 4 columns are brace to each other by large rectangular beams forming a vierendeel frame
The connection of masts is made by a pinned type one and between slabs by a fix connection
Two three-story high cross braces are located on both ends of the inner atrium and provide additional North-South stabilization
