Your Design Journal entries for this module should highlight:
- your overall strategy and the features of the structural system
The structural design needs to fit the geometry of the building. The most important strategy is to use several layers of hexagonal beam systems to accommodate the round and flower-like building. Regular beam systems would not work. The columns in the middle are the thickest. The exterior columns are slanted. Sloped beams support the roof. There are structural walls, but there are also curtain wall systems and patios, so there are columns on the edges.
- the material and framing system selected
Steel columns and steel beams are used because the whole building is modern-style, and there are lots of curtain wall systems. Round columns and beams are used to fit the building geometry.
Thickest central columns: HSS-Round Hollow Structural Section-Columns: HSS20X0.500
Regular columns: HSS-Round Hollow Structural Section-Columns: HSS12.750X0.250
Beams: Round Bars: RB 10
- the locations of structural columns and major framing elements
Columns appear in the appropriate locations, mostly inside the walls and at intersections of walls. Some are exposed in the room and on the patios. Since the shape is round, they could be revealed. They are not designed to block entrances. Columns in the outside layer are slanted to fit the structure. Both columns and beams are distributed throughout the whole building structure. The largest span of beams is less than 30 feet. Beams are organized in hexagonal layouts. There is space left for the atriums and stairs in the middle. But there are beams under the skylight to support the roof. Beams on the top level are sloped to support the roof since the roof is not flat.
- any special structural challenges
The biggest challenge is the slanted walls and sloped roofs. This special feature cannot be supported by regular column and beam systems. Some of the columns and beams are slanted or sloped. The second challenge is the layout of the building. I used a hexagonal layout to support the flower-like building. Regular beam systems would only work for buildings with rectangular floor plans. The maximized span of beams cannot be too long as well, so there are extra columns to support the beam system.
