Etabs Mass Summary By Story Page

If the weight for a story is zero, check that the diaphragms are properly assigned and the materials are defined with a non-zero density. Conclusion

ETABS determines story mass based on your definition ( Define > Mass Source ). Typical Mass Source Configurations etabs mass summary by story

of Live Load, depending on local code requirements like ASCE 7 or Eurocode 8). If the weight for a story is zero,

The ETABS output table contains several key columns. Here is what they mean: The ETABS output table contains several key columns

This report is the primary tool for checking the "Mass Source" definition and ensuring that the dead loads, live load percentages, and self-weight are accurately represented at each floor level. How to Access the Mass Summary Table

Understanding ETABS Mass Summary by Story: A Comprehensive Guide

The is an essential verification tool. It provides a detailed, floor-by-floor breakdown of mass and inertia, allowing engineers to confirm that their model accurately captures the building’s weight. By understanding the mass source and reviewing this table, you ensure that the seismic design is safe, realistic, and compliant with structural standards.
