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

1)

Aim :-

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

Procedure :-

Slab Design

* Open the previous week done tekla model

* Run the first order analysis

* First go to the ground floor and untick the members,grids and dimensions

* Select all slabs and provide T10,200 mm spacing for both top and bottom

* Select all the slabs and Design slabs

* Now select the first slab,right click – Check Panel

* Note that the top bars are failing in moment capacity

* Lets try increasing the bar dia or decreasing the spacing

* Now right click to check the panel

* The panel is safe now. Lets repeat the procedure for other slabs too

* If the panel fails in span to effective depth ratio, then try to increase the depth of the slab so that the l/d ratio is within limits

* If a panel fails in moment capacity check, then find the required diameter from the Ast required and assumed spacing and then design the panel

* Ensure that all slabs pass the design criteria

* Repeat the same procedure for the first floor also

Foundation Design

* Go to Design – Settings

* Under Isolated footings, check Reinforcement layout, Foundation size, General parameters, Piles

* Now go to Foundation – Catalogue

* Click on Add

* Add the details of the pile

* Go to Base level

* Foundations – Pile cap column

Result :-

Successfully complete to design the slab and foundation of the model. Outline the thought process for designing of the elements (column, beam, slab and foundations)
