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

Aim:

• To design the slab and foundation of the model.
• To outline the thought process for designing of the elements (column, beam, slab and foundations)

Procedure:

• Open the RCC TSD file.
• Slab design:
• Go to G.L, uncheck all members other than slab items
• Click a slab and check its property like reinforcement, bar diameter and spacing in the property window
• Right click on a slick -> check panel.
• Go to review and check it.
• Now change the reinforcement and spacing to increase the area of reinforcement to pass the design
• Check all other slab by check panel
• Adjacent slab has failed.
• So, make changes in reinforcement and spacing to get uniformity for easy construction
• Similarly to go F.L and check the panel and do the changes to get the member pass and uniformity for easy construction.
• Go to R.L and follow the same procedure
• Go to 3D Structure to have a look.
• All slab items are passed.

Foundation design:

Pile foundation

• Analyze the model and check the reaction
• Designing the pile:
• Go to Design -> settings -> Foundation ->piles and give the following settings.
• Go to foundation -> Catalog and give the following values.
• Modelling and design:
• Go to Base level
• Click foundation -> pile cap column and click on each column.
• Now right click a column -> select design member
• After designing right click the pile ->select check member
• Similarly follow the same procedure for all the column.
• Go to review view and select the status for pile cap
• Select status for piles
• Select ratio to check the ratio

Result:

• Hence the slab and foundation are designed.

• General thought process for designing of the elements (column, beam, slab and foundations)

  • Step 1: The members have to be created with a property in manage property set
  • Step 2: Then model the members according to the plan
  • Step 3: Apply the load like wind load, seismic load, dead load, live load, member load.
  • Step 4: Analyze the members by its bending moment, shear force, axial force, deflection.
  • Step 5: Finally design each member by check member option.
