Ans 1:- Aim:- To model Rc structure analyse and design the model elements as per IS codal provisions

PROCEDURE:-

1. B Open A New Tekla template in Tekla

Go to settings from home tab

1. Assign the design codes and units to be considered in the model
2. Define the structural default setting
3. Click on ok

Step 1:- to define the construction levels

1. Click on the construction levels from the model toolbar
2. Then add the levels in the dialoge with a given spacing
3. Click on ok
4. 

   Step 2:- to draw horizontal and vertical grids

   1. Click on the the grids icon from the model toolbar
   2. Specify the first point and drag to draw the first grids
   3. Then select on the parallel quick grids to draw the other grids lines with a given spacing
   4. Similarly draw the vertical grids also

      Step 2:- to draw horizontal and vertical grids

      1. Click on the the grids icon from the model toolbar
      2. Specify the first point and drag to draw the first grids
      3. Then select on the parallel quick grids to draw the other grids lines with a given spacing
      4. Similarly draw the vertical grids also

      5. Step 3:-

         To assign the model elements like columns, beams and slabs

         1. Go to mange property sets from the home tab
         2. Click on new then members and concrete column
         3. Then define the size of the column and grade of concrete
         Click on ok Now define the properties of slab and assign slab panels to the modelCrate frames
      6. To addd wall panels to the model
      7. Select the wall panels from the tab
      8. Then assign them to the model
      9. 

         Ste[p 4:-

         To model the staircase

         1. Firstly switch of the slab items in scene content
         2. Select the stair area
         3. Right click and add to sub structure
         4. 
         5. Double click on stair
         6. Go to model and then click sloped planes
         7. 
         8. Define the stringer beams
         9. 1. Draw the stringer beams
            Anand right click on add to substructureNext we have o offset the grid for that go to plan
            1. To draw the staircase firstly we need to create a sloping planes
            2. To create a slope planes select the slopes from the model tab
            3. Then click on the nodes to create a sloping planes
            4. Then click on the beam and add them to a loping planmes
            5. On which we can place a waist slab
            Go to manage property and define the slab
            1. After defining the stair slab model the slab
            2. Untick the include in diaphragam as sloping slab can not be act as diaphragam

            Caclculation of loads

            1. Self weight of slab is directly taken by Tekla model
            2. Dead load of floor finishes
            3. Assume the thickness of floor finish 80 mm
            4. Unit weight of concrete is 24 kN/m^3
            5. Dead load due to floor finish =0.08*24=1.92jN/m^2
            6. Brick wall loading
            7. Assume the unit weight of bricks as 20 kN/m^3
            8. Thickess of exterior wall =230 mm
            9. Interior wall thicknesss=150 mm
            10. Height of the Ff =3.5 m
            11. Height of second floor=3.7 m
            12. Brick wall load on gf (exterior wall=3.5*0.23*20=16.1kN/m
            13. Brick wall load on gf interior wall=3.5*0.15*20=10.5kN/m
            14. Brick wall load on ff (exterior wall=3.7*0.23*20=17.02kN/m
            15. Brick wall load on ff (interior wall=3.7*0.15*20=11.N/m
            16. Roof loading is assumed to be 1.5 kN/m^2
            17. Floor finish load applied on slab panels
            18. 

                Calculation of live loads

                3. Live loads are calculated as per is 875 part 2

                   Step :- Wind load application

                   1. For wind load application first we have to create the wall panels
                   2. Wind speed-50 m/s^2

                   Horizontal dimension-36 m

                   Lesser horizontal dimension-16m

                   Height of the building-8.35 m

                   Ratio of wall and roof coefficient

                   Wall-l/W=2.25

                   Wall h/w=0.52

                         After analysis go to review tab and select on slabs design
                      6. Design of slab go to design and select analsys and design
                      7. 
                         1. we can see that all the slabs are passing
                         Now to design beams click on design analysis and design
                      8. Right click and select the interactive design
                      9. Similarly select the columns and right click and select interactive designs
                      10. Similarly we can get repotts and design for beams
                      11. Click on report tab inorder to get the report
                      12. Hence we have designed the building.
