To calculate the dead , live and wind load for RC residential structure and to apply them using TSD

1.AIM:

To Calculate dead load in design report based on IS code and apply dead load on the model

• Finishes of 50mm
• Slab thickness as per the design
• Brick wall load
• Roofing load

Procedure:

2.AIM:

To Calculate live load in design report based on IS code and apply dead load on the model

Procedure:

Dead loads:

• Go to Load – Load Cases
• Check the load cases

Live Loads:

• Now lets apply the imposed load to the model by checking the layout
• Lets first go to GF and apply the loads

3.AIM:

To Generate manual wind loading in the design report based IS code as per the following input

• Basic wind speed = 50m/s
• Terrain category 2

Step 1: Finding Design Wind Speed:

• Referring to IS 875 P3, Vz = Vb k1 k2 k3 k4 according to Cl 6.3
  • Where Vz – Design wind speed
  • K1 – probability factor
  • K2 – terrain roughness and height factor
  • K3 – topography factor
  • K4 – importance factor for cyclonic region
• From table 1, k1 = 1
• From table 2, for height of the building 10 m and terrain category 2 , k2=1
• From Cl 6.3.3 , k3 = 1 since, theta < 3(flat terrain)
• From Cl 6.3.4, k4 = 1 for general structures
• Substituting all the above values, Vz = 50 * 1 * 1* 1 * 1 = 50 m/s

Step 2: Finding Design Wind Pressure:

• From Cl 7.2, wind pressure, pz = 0.6 Vz^2
  • pz = 0.6 * 50 ^ 2 = 1500 N/m2
  • pz = 1.5 kN/m2

Step 3: Design Wind Load:

Wind Load on Wall:

• From Cl 7.3.1, F = (Cpe – Cpi) A pz = Cp * pz
• Cpe is found from Table 5 of IS 875 P3 for h/w and l/w ratios
  • h/w = 9 / 10.7 = 0.84
  • l/w = 19.225/10.7 = 1.80

• Lets consider medium openings in which Cpi = + 0.5 / -0.5 according to Cl 7.3.2.2 of IS 875 part 3

4.Aim:

To apply the loadings on the model based on the above loadings

Wind + Y + Cpi:

Wind + Y – Cpi:

Wind + X + Cpi:

Wind + X – Cpi:
