wool:NZ (Wind AS/NZS 1170.2)

Calculate building response due to wind as per the AS/NZS 1170.2 2011 Wind Code

wool:NZ (The Wind Tool) is the pocket calculator which determines building response as per the New Zealand national wind-loading code AS/NZS 1170.2 2011.

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 New Zealand.

wool:NZ is possibly the best thing since the invention of the Boundary Layer Wind-Tunnel

★ Design your own building and calculate along-wind and cross-wind responses for four wind directions:

* Base Overturning Moments

* Base Shear Forces

* Torsion

* Maximum Tip Deflection

* Maximum Tip Acceleration

★ Calculate and plot along-wind and cross-wind responses over the height of the building:

* Point Loads

* Shear Forces

* Deflection

* Torsion

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

* Basic building dimensions (HxLxD)

* Frequencies of vibration, assumed structural damping and mode shape exponents (pre-sets as defined by AS/NZS 1170.2 commentary)

* Return period, upstream terrain category and regional wind speed (with hi-res map of various wind regions of New Zealand)

★ Advanced controls available for the experienced engineer:

* Topographic Multiplier (Mt)

* Shielding Multiplier (Ms)

* Directional Multiplier (Md)

* Action Combination Factor (Kc)

* Eccentricity creating torsion

* Building density

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

★ Save projects and edit later

★ SI Units
