LOAD CALCULATION


Effective Depth (d) = D - Cover = 150 - 20 = 130 mm

Self-weight = 0.15 × 25 = 3.75 kN/m²  
Total Load (w) = 3.75 + 1.0 + 2.0 = 6.75 kN/m²

For design, use ultimate load:
Factored Load (wu) = 1.5 × w = 1.5 × 6.75 = 10.13 kN/m²
Mu = (wu × Ly²) / 8 = (10.13 × 4²) / 8 = 20.26 kNm/m
Ast = (Mu × 10⁶) / (0.87 × fy × jd)
Assume jd = 0.9 × d = 0.9 × 130 = 117 mm

Ast = (20.26 × 10⁶) / (0.87 × 500 × 117) ≈ 398.6 mm²/m
Area of 10 mm dia bar = π/4 × 10² = 78.54 mm²

Spacing = (1000 × Area of 1 bar) / Ast  
= (1000 × 78.54) / 398.6 ≈ 197 mm → Provide @ 180 mm c/c
Ast(min) = 0.0012 × b × D = 0.0012 × 1000 × 150 = 180 mm²/m < Provided ✔
Required d = √(Mu × 10⁶ / (0.138 × fck × b))  
= √(20.26 × 10⁶ / (0.138 × 25 × 1000)) ≈ 76.6 mm < 130 mm ✔

Parameter                                       Value
Factored Load (wu) 10.13 kN/m²
Design Moment (Mu) 20.26 kNm/m
Required Ast 398.6 mm²/m
Provided Reinforcement 10 mm @ 180 mm c/c
Effective Depth 130 mm
Slab Thickness 150 mm

 DL, LL, WL, EQL Load Calculations 

This follows the IS 875 parts:

Load Type Code Reference
DL (Dead Load) IS 875 Part 1
LL (Live Load) IS 875 Part 2
WL (Wind Load) IS 875 Part 3
EQL (Seismic) IS 1893 (Part 1): 2016

1. DEAD LOAD (DL)

a) Self-weight of slab:
Slab thickness = 150 mm = 0.15 m
Unit weight of RCC = 25 kN/m³
Slab weight = 0.15 × 25 = 3.75 kN/m²
b) Floor finish:
Finishes (tiles/mortar) = 1.0 kN/m² (IS 875 Part 1 typical)
c) Wall Load on Beam (external wall):

Item Value
Wall Thickness 230 mm
Wall Height 3.5 m (storey height)
Density of brick 20 kN/m³
Load 0.23 × 3.5 × 20 = 16.1 kN/m (UDL on beam)
2. LIVE LOAD (LL)

From IS 875 Part 2 (Residential Building):

Room Type Live Load (LL)
Rooms, Living 2.0 kN/m²
Bathrooms, etc. 2.0 kN/m²
Balconies 3.0 kN/m²

➡️ Take LL = 2.0 kN/m² for general slab design
3. WIND LOAD (WL) — as per IS 875 Part 3

Assumptions:
Location: Bangalore
Wind Zone = Zone II
Basic Wind Speed (Vb) = 33 m/s
Building height = 28 m
Terrain Category: 2
Class: B
a) Design Wind Pressure (Pz):

 $Pz = 0.6 × Vz² Vz = Vb × K1 × K2 × K3 Assume: K1 = 1.0 K2 (for 28 m) ≈ 1.05 K3 (Topography) = 1.0 → Vz = 33 × 1 × 1.05 × 1 = 34.65 m/s Pz = 0.6 × (34.65)² ≈ 720.3 N/m² = 0.720 kN/m²$ Pz=0.6×Vz2Vz=Vb×K1×K2×K3
Assume:K1=1.0K2(for28m)≈1.05K3(Topography)=1.0→Vz=33×1×1.05×1=34.65m/sPz=0.6×(34.65)2≈720.3N/m2=0.720kN/m2
b) Wind Load on vertical surface:

For a wall area 3.5 m × 4 m = 14 m²:
Total force = 0.72 × 14 = 10.08 kN
Distribute this as nodal or member loads in STAAD.
4. EARTHQUAKE LOAD (EQL) — IS 1893:2016

Assumptions:

Parameter Value
Zone (Bangalore) Zone II → Z = 0.10
Importance Factor (I) 1.0
Response Reduction (R) 5 (SMRF)
Soil Type II (Medium)

Base Shear (VB):

VB = Ah × W  
Ah = (Z × I × Sa/g) / (2 × R)  
Assume Sa/g = 2.5 (for medium soil, T < 0.4s)

Ah = (0.10 × 1 × 2.5) / (2 × 5) = 0.025  
Total seismic weight (W) = DL + LL for all floors

Let’s assume:
W = 6.75 kN/m² × 25 m × 16 m × 8 floors = 6.75 × 400 × 8 = 21,600 kN

→ VB = 0.025 × 21,600 = **540 kN**

This will be distributed along the height of the building based on floor masses.
