5

Typical start: 1.15. Accepted range: 0.5-2. This value is validated before calculation.

Default 1.15
Range 0.5-2
6

ASCE-style Kz factor. Use 1.0 for early screening when exposure is not set.

Default 1
Range 0.3-3
7

ASCE-style Kzt factor. Use 1.0 when no topographic speed-up is applied.

Default 1
Range 0.5-3
8

ASCE-style Kd factor from the applicable wind procedure.

Default 1
Range 0.5-1
9

ASCE-style Ke factor. Use 1.0 when elevation correction is not applied.

Default 1
Range 0.5-1.5

Use case

Estimate wind force before exposure risk turns into rework.

Use wind speed, area, and drag to generate a fast load estimate.

Trusted inputs

ASCE pressure shortcut

Range notes

Supports imperial mph/ft² and metric m/s/m² inputs.

ASCE-style Kz, Kzt, Kd, and Ke factors default to 1.0 for screening.

Steady-state estimate; does not replace full wind design procedures.

Important

Engineering estimate only. Validate with project wind-code requirements.
