The program outputs detailed intermediate calculations for the generation of wind pressures on building surfaces using ASCE 7 28.1.2 for low buildings and 27.1.2 for buildings of all heights.
It is possible to edit this output in the Shearwalls viewer with insertions and deletions, and to copy information with Ctrl-C. The following data are output.
