What is difference between rigid steel frame and portal steel frame
Aspect | Rigid Steel Frame | Portal Steel Frame |
|---|
Design | Rigid connections in multi-story configurations | Rigid connections in single-story portals |
Applications | Multi-story buildings ( offices, apartments, hotels) High-rise structures Industrial facilities with heavy loads Bridges and infrastructure projects | Single-story industrial buildings (e.g., warehouses, factories) Agricultural buildings (e.g., barns, storage sheds) Aircraft hangars Large retail spaces (e.g., supermarkets, showrooms) |
Span | Short to long spans | Large spans (20-60 meters) |
Height | Suitable for tall structures | Limited to low-rise structures |
Cost | Higher cost due to complexity | Cost-effective for single-story buildings |
Construction Time | Longer construction time | Faster construction |
Lateral Load Resistance | Excellent resistance | Moderate resistance |
