Auto Load Calculation

Self Weight

Self-weight can be included in any static load case by increasing self weight multiplyer.

Auto Seismic Load

Program support Auto Seismic Load according to UBC 97. Minimum equivalent lateral load is applied on each node according to their mass lumped at node.

Response Spectrum Analysis

After modal analysis (Eigen Method), It calculate response spectrum analysis as mention in UBC 97 Code.

Analysis Types

Software is capable to solve following analysis.

1) Static Linear Analysis

2) Modal Analysis (Free-Vibration)

3) Response Spectrum Analysis
