Yes I have the current frequency of 50Hz. But I am not sure what effect this would have on a large concrete block foundation almost a meter thick. What effect does this frequency have on the concrete base?
I am looking for some literature references which can assist with the design of large block foundations for various heavy equipment in substations (eg 11000 kg Transformer). As the loads on the foundation are static and the base area is large, bearing pressures under the base are not normally an...
The topic is a question about raft/mat foundation for steel lattice towers.
Raft foundations should resist the overall overturning moment of the tower by a factor of safety of 1.5 (depending on the spec). For a rectangular raft we should satisfy (ex/bx)^2 + (ey/by)^2 <= 1/9 to meet the factor of...
