Lateral Load Calculator (Wind + Seismic)

Expert Guide

Combined tool for calculating wind pressure and seismic forces acting on buildings in Nepal seismic zones.

Professional concrete staircase construction with risers and treads at building site

⚡ Quick Answer

Nepal falls primarily in Seismic Zone V (Z=0.36). Base Shear Vb = (Ah × W) where Ah = ZI/2R × Sa/g. For site-specific seismic design reports, visit pro.nirmansutra.com.

🛠️ How It Works

Select the lateral force type (Wind, Earthquake, or Soil).
For seismic: enter total seismic weight, Zone Factor, and response reduction (R).
The tool calculates design base shear as per IS 1893:2016.
For detailed floor-wise seismic force distribution, see our Seismic Design Blog.

📋 Real-Life Example

Example: Seismic Base Shear for 5000 kN building (Zone IV, I=1, R=3):
1. Ah = (0.24 × 1) / (2 × 3) = 0.04.
2. Vb = 0.04 × 5000 = 200 kN.
3. This is distributed across floors based on height and mass.

❓ Frequently Asked Questions

Which seismic zone is Kathmandu in?

Kathmandu and most of Nepal are in Seismic Zone V (highest risk) with Z=0.36 as per IS 1893. Use this in all structural designs.
