wool:BRA (Wind Code NBR 6123)

Calcola risposta edificio a causa del vento secondo il brasiliano Codice vento NBR 6123

wool:BRA (The Wind Tool) is the pocket calculator which determines building response as per the Brazilian national wind-loading code NBR6123 for a 50 year return period.

The perfect tool to aid engineering professionals, students and teachers in the calculation and verification of the design of mid-rise and tall-buildings in Brazil.

wool:BRA is easily the best thing since the invention of the Boundary Layer Wind-Tunnel

★ Design your own building and calculate the following responses for wind along two-orthogonal directions:

* Base Overturning Moments

* Base Shear Forces

* Maximum Tip deflection

* Torsion

★ Calculate and plot the following over the height of the building:

* Static, Dynamic and Total Wind Loads

* Shear Forces

* Deflection

* Torsion

★ Easy to use interface with minimal inputs required from the user:

* Basic building dimensions (HxLxD)

* Mode shape exponents, frequencies of vibration and assumed structural damping (pre-sets available for typical structures)

* Upstream terrain category and regional wind speed (with hi-res map of Brazil to aid in the selection of regional wind speed)

★ Advanced controls available for the experienced engineer:

* Topographic Multiplier

* Time-average interval of response (ranging from 3 seconds to 1 hour)

* Choice between high and low turbulence models

* Eccentricity creating torsion

* Building density

★ Outputs important parameters used in the calculation of building response for user reference:

* Project velocity

* Project dynamic pressure

* Drag coefficients

* Dynamic amplification factors

★ Save projects and edit later

★ SI units

★ Help Buttons to assist with unknown parameters
