Special Seismic Load Effects
- ETABS can automatically calculate the Rho factor, which is a reliability factor based on system redundancy
- ETABS calculates the Rho factor in accordance with Section 1617 of the 2000 International Building Code
- The Rho factor is only calculated when there is lateral load present in the model.
- Display loading values
- Color contoured area loading diagrams
Automatic Code Based Wind Loading
- Automatic permutation of wind directions and eccentricities
- ETABS will automatically generate wind loads based on various domestic and international codes including but not limited to:
- UBC 94; 97
- BOCA 96
- ASCE 7-95; -02; -05
- NBCC 2005
- Mexican
- Chinese 2002

- Strength and service combinations
- User-defined load combinations
- Linear add, envelope, absolute add, SRSS, and range combinations
Area, Line, Point and Thermal Loads
- Uniform or non-uniform surface loads (surface loads can be assigned in any direction, not just gravity)
- Point loads can be assigned in any direction, including skewed angles
- Uniform or trapezoidal loads on lines in any direction
- Thermal load can be assigned to joints, lines and/or areas
- Imposed joint support displacement
Automatic Live Load Reduction
- Live load reduction options:
- Tributary Area
- Influence Area
- User parameters
