To Design slab and foundation for an RC residential building using TSD

Answer of the queestion

Aim: Aim is to Design the slab and foundation of the model. Outline the thought process for designing of the elements (column, beam, slab and foundations).

Procedure:we have to follow the folowing steps:-

Step-1

• First We to first floor in scene view.
• In scene content, untick grid lines and members, so that only slab members can be seen.
• After run analysis, select slab 12 to check panel.

Step-2

• area of reinforcement provided is more than the area of reinforcement required, go to property window, change reinforcement spacing to 175mm for 10mm diameter bar.
• Now again check the panel

Step-3

• As it is select the identical slab of SL12
• In the property window, change the reinforcement spacing to 175 mm as provided
• remove the slab portion and again provide slab on beam
• put dead and imposed load on the newly created slab.
• the model to check any error.

Step-4

• again provide overall depth 150 mm and reinforcement diameter of 10mm at 175mm centre to centre.

Step-5

• For roof floor, provide secondary beams between grid line A, B and C.
• Delete the slab portion and again provide slab on beam
• Apply dead and imposed load on the newly created slab.
• Validate the model to check any error.

Foundation Design

• Under Isolated Foundation, select pile cap for reinforcement settings.
• Set minimum loose bars as 16mm diameter.

Step-6

• Go to base floor, set pile type in catalogue.
• Edit data, materials and pile capacity for piles.

Step-7

• in the property window, change the property for PC1 pile.
• Size 2.05m x 0.8m x1m. M30 grade of concrete
• Pile spacing= 1250mm with reinforcement diameter of 20mm at 150mm c/c spacing

Step-8

• Select isolated pile cap column
• Pick the C2 location to create column isolated pile cap position.
• Design the member
• In the property window, change the property for PC2 pile.
• Size 2.05m x 0.8m x1m. M30 grade of concrete for 2 pile
• Pile spacing= 1250mm with reinforcement diameter of 20mm at 150mm c/c spacing
• Check the member satisfy the design condition.
• In review view, check the status of the pile cap.
