I need mathematical methods for determining the bearing stress of a circular footing where the overturn moment is the dominant factor. If the foundation is starting "lift at the heel", ie the whole surface is not in contact with the soil, the geometry of the footing rapidly changes as...
Is there any recognized method of determining and/or including the metal sheeting stiffness to control possible buckling of slender trusses, spans approx 25-30m long. The same for columns. What method can be used, and what are the limits?
I am looking for a satisfatory method of designing circular "donut" shapes baseplates / flanges subjected to bending moments, such as baseplates of monopole masts. Up to now I used an empirical method based on "common sense".
I see you are from Gabs, Botswana. I am from Jhb, SA. Have you looked at SABS 0225, the SA lightmast design codes? We use these to design the cell phone monopoles, and from your sizes, this falls right into this category. Vortex shedding is mentioned, but only briefly, as local buckling in...
