Facade zone for preliminary net pressure

Zone selection uses simplified preliminary coefficients only. It is not a substitute for project-specific facade pressure zoning.

Preliminary IS 875 inputs
Preliminary IS 875 estimate only. Engineer Verification Required.
m/s
Basic wind speed for the preliminary IS 875 wind pressure estimate.
Terrain category used for the preliminary terrain-height factor estimate.
Structure class used for the preliminary terrain-height factor estimate.
m
Building height used for the preliminary IS 875 wind pressure estimate.
Risk coefficient used in the preliminary design wind speed estimate.
Topography factor used in the preliminary design wind speed estimate.
Captured for future workflows; not used in the beta preliminary pressure estimate.
Captured for future workflows; not used in the beta preliminary pressure estimate.

These fields drive a preliminary IS 875 wind pressure estimate only. This does not establish IS 875 compliance, final wind pressure, structural design approval, or glass verification.

Preliminary engineering assumptions
-Preliminary net pressure estimation only.
-Available wind pressure is treated as the preliminary velocity/design pressure basis.
-Positive net pressure uses q x abs(Cpe + Cpi).
-Negative net pressure uses q x abs(Cpe - Cpi) and is reported as suction.
-The governing pressure is the larger absolute value of positive and negative net pressure.
-This module does not perform ASTM E1300 or IS 16231 glass verification.
-Typical facade field screening coefficients.
Warning: Glass-to-glass sealant joints are not considered structural side supports.

-Preliminary location-based estimate only. Engineer Verification Required.
-This does not establish wind-code compliance, final wind pressure, or final glass design.
-Coefficients simplified.
-Zone effects simplified.
-Not suitable for engineering approval.
-Engineer Verification Required.
-Monolithic glass may require additional review for safety and post-breakage requirements.
Engineering notes

System: Slab-to-slab U-channel glazing (top & bottom channels only)

Structural model: Two-edge supported vertical spanning glass panel.

Wind codes determine wind pressure basis. This beta workflow provides preliminary concept design screening only. Engineer Verification Required.

Wind workflow resolves pressure source and status for concept design screening only. It does not establish IS 875 or ASCE 7-16 compliance.

Facade pressure architecture: Wind Speed -> Velocity Pressure -> Cpe -> Cpi -> Net Pressure -> Governing Pressure -> Glass Verification.

Future facade zones: Field Zone, Edge Zone, Corner Zone.

The Economy, Balanced, and Conservative options are generated by a conservative preliminary glass verification screening engine and are not final designs.

Current MVP Limitations
-Preliminary concept design screening only - not final glass design
-ASTM E1300 not implemented
-IS 16231 not implemented
-Net pressure coefficients not yet fully implemented
-Engineer Verification Required by a qualified engineer
Coming Next
