Professor A. L. L,. Baker, in his simple solution for wind stresses in multi-storey buildings, aims at defining the limits in any stanchion within which the point of contraflexure must lie. This enables safe estimates to be made or bending moments due to wind load in both stanchions and beams. The theory is based upon the analysis of a single bay multistorey frame with equal storey heights and equal beams, and would only apply strictly to such a building. The solution also assumes that the joints are completely rigid. However, the extreme ease with which the theory may be applied when only the barest outline of the design is settled makes it attractive, and prompts investigation into what happens when the conditions laid down in the simple analysis are not satisfied.
