wool:BRA (Wind Code NBR 6123)

Features wool:BRA (Wind Code 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
