When a building is found to be tilted, it is typically an indication of some serious problems occurred in the building. The Leaning Tower of Pisa is a famous example of tilted buildings due to differential settlements. Today, however, tilted buildings are intentionally designed and architecture, as are the cases with the Gate of Europe Towers of 1996 in Madrid designed by Philip Johnson/John Burgee, Veer Towers of 2010 in Las Vegas by Helmut Jahn.
The structural performance of a tilted tall building is dependent upon its structural system and angle of tilt.
shows example tilted tall buildings. Compared to the perimeter tube type structures, such as braced tubes and diagrids, the outrigger system provides greater lateral stiffness for tilted towers because of the triangulation of the major structural components – the braced core, outrigger trusses and mega-columns – caused by tilting the tower, as can be seen in the pic.
Tilted diagrids (elevation view), braced tube (elevation view) and outrigger structure (section view).
Sixty stories tilted tall buildings of various structural systems are studied in this section. The angles of tilt studied are 4, 7, 9 and 13 degrees, which correspond to offsets of 0, 12, 16 and 20 stories, respectively, at both top and bottom of the structure. The pic shows braced tube structures with these angles of tilt. Diagrids and outrigger structures are also tilted with these angles. Pics summarizes wind-induced maximum lateral displacements of the 60-story tilted braced tubes, diagrids, and outrigger structures.
The lateral stiffness of the braced tube and diagrid systems is not substantially influenced by the angle of tilt between 0 and 13 degrees studied here. The lateral stiffness of the outrigger system is even increased by tilting the tower due to the triangulation of the major structural components – the braced core, mega-columns and outrigger trusses. Tilted tall buildings are subjected to significant initial lateral deformations due to eccentric gravity loads.
Gravity-induced lateral displacements increase as the angle of tilt increases in all the three structural systems. Among them, the outrigger structures produce relatively small gravity-induced lateral displacements again because of the
triangulation of the major structural components. These gravity-induced deformations can be managed substantially through careful construction planning. As the angle of tilt increases, very large localized stresses are developed in tilted tall buildings.
Though the structural complex design of tall buildings is generally governed by lateral stiffness, careful studies on satisfying strength requirements are also essential for tilted tall buildings. Large tensile forces, not very often found in conventional vertical tall buildings, can be developed in tilted tall buildings.
Careful design studies on the connections of the tensile members of tilted tall buildings are required.
3D Design or Architectural Concept
For this type of structure, you have to learn first the Massing part in Revit Architecture.Each and every part is very important to learn the Revit Architecture.basically if you want to know the critical or complex structure to make then you have to know the Massing portion.
Massing is the basically the way you can draw your complex structure very easily, start from rotating to the Twisted and tilted structure you can create very easily.the various option gives you the platform to do that easily.
