ShedSafe Site Specific Design Criteria TSSC214004

Execut ive Summary - Sit e Specific Analysis

The design analysis of the building has not been considered for each of the 4 orthogonal directions.
Hence the maximum wind speed in any of the 8 cardinal directions has been used as the design wind
speed. This is a conservative approach.

Each cardinal direction has been considered and the results are summarised below
