Professional tool for calculating structural loads including dead, live, wind, snow, and seismic loads.
Structural design requires considering various combinations of loads acting simultaneously.
Most common combination for gravity load design.
For design considering wind loads with reduced live load.
For earthquake design with snow load consideration.
For overturning and sliding stability checks.
Note: Load factors may vary based on design codes (ASCE 7, IBC, Eurocode, etc.). Always verify with local building codes.
Proper load calculation is essential for safe and efficient structural design. Different types of loads act on buildings in various combinations.
Key Insight: Structural design must consider both the magnitude of individual loads and their likely combinations.
Permanent static loads from structural elements and fixed equipment.
Variable loads from occupancy, furniture, and movable equipment.
Loads from natural phenomena that vary by location and building characteristics.
Loads specific to building function or unusual conditions.
| Material | Density (kg/m³) | Compressive Strength (MPa) | Tensile Strength (MPa) | Elastic Modulus (GPa) |
|---|---|---|---|---|
| Concrete (C25) | 2400 | 25 | 2-3 | 25-30 |
| Structural Steel | 7850 | 250-400 | 250-400 | 200 |
| Reinforcement Steel | 7850 | 500 | 500 | 200 |
| Timber (Softwood) | 450-550 | 5-10 | 8-15 | 8-12 |
| Masonry | 1800-2200 | 5-20 | 0.5-2 | 5-15 |
Structural design follows these fundamental principles:
Professional Note: This calculator provides preliminary design values. All structural designs should be verified by a qualified structural engineer before construction, especially for critical or complex structures.
