Combined Footing

FEM Analysis of a Tank Foundation

Structure
: Pile Foundation (SC, PHC)
Scale
: Diameter 5.0m, Height 13.0m
  Weight350t/Footing(During Operation)
Number of stories
Structural Form
Design Code
: Building Standard Law and Order Enforcement、Building Foundation Structural Design Guidelines、Vessels Structural Design Guidelines with Commentary
Since a number of tanks will be installed on one foundation, design was conducted considering the interphase of the tank.

With the tanks installed densely on one foundation, the arrangement of the piles was planned in a manner of which the immense weight will be transmitted to the piles without difficulty.

Since liquefaction occurs at 200gal, a liquefaction range must be considered appropriately in the design.
For the tank load during an earthquake, load due to sloshing must also be considered.

Manufacturing Building

(Certain Country) Construction Manufacturing Building inside a Plant

Structure
: Steel Structure
Scale
: 1400m2 Eaves
  Height: 15.0m
Number of stories
: 2 floors
Structural Form
: Transverse Direction:Rigid Frame Structure Longitudinal
  Direction: Braced Frame Structure
Design Code
: British Standards
The 2nd floor deck slab was modeled as a solid and floor stiffness was considered in the design.
The number of braces used was minimized in the design.
The pedestal of the column base was also modeled and the upper frame down to the ground beam was analyzed in series.
For large and heavy equipment, consideration was made so that the horizontal force can be effectively transmitted during an earthquake.

PIPERACK

(Certain Country) Main Piperack Supported inside a Plant

Structure
: Reinforced Concrete Structure and Steel Structure
Scale
: Length/ 220m
  Width:14m / Height:15m
Number of stories
: 3 Floors
Structural Form
: Transverse Direction: Rigid Frame Structure Longitudinal
  Direction: Braced Frame Structure
Design Code
: AISC,ACI
Design was performed with expansion joints at every 50 meters.
For cost reduction as well as fireproofing, the first floor and the second floor was designed as reinforced concrete structure.
