woolite:BRA (The Free 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.
woolite: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) *restricted in free version*
★ 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
* Modal forces
* Calculation critical integrals
★ Save projects and edit later
★ SI units
★ Help Buttons to assist with unknown parameters
