Design Journal Entry - Module 8
Your Design Journal entries this week should highlight your design thinking that influenced your decisions about:
- your overall strategy and the features of the structural system
- the material and framing system selected
- the locations of structural columns and major framing elements
- any special structural challenges
my overall strategy is using steel to construct my whole building and during the way, I will leave the room for my opening area, elevator and stairs. Also, because my structure is like layers by layers and bigger and bigger as it goes up, so I also use a a circle of steel on the outermost layer to ensure support and stability.
Also, because different layers have different area and design so I choose different grid for different level to make sure that the column will not show up just in the hallway. As you can see, for level 1 is A,B,C,D,E,F,a,1,2,3,4; for level 2 is A1,A,B,C,D,E,F,G,0,1,1-1,3-1,4,5; for level 3 is A0,A,B,C,C1,E1,F2,H,-1,1-2,2,3,1-3,1-4,6; so that it can fit for each layer.
The main material I choose is steel column W10*49 which I think is more suitable for my building because first, it has strength and durability, it is near the sea so it also need to consider its seismic performance; second, it has better flexibility and plasticity, also a faster construction speed which is really suitable in NY; third, it is sustainable material. As for the beam, to fit my column I choose W 14*30 and for the beam system.
As for some special design, I make elevation from level and z-axis offset about -0’10’’ for the beam so that it can better fit the floor and for the outlier structure I use . Also because of my architecture design, I try to use some tilted columns to provide support so that it can be more stable.
What is more, I add the isolated foundation for the bottom of the base columns.
