Abstract:
A new type of saddles has been successfully used showing how horizontal stresses can be shared. Commonly asymmetric foundations can be symmetrically built. The damage and stresses in anchor bolts can be reduced, lowering costs and increasing reliability of foundations. The design of this "rotating saddle" was born as a need to solve or alleviate the problem of stresses due to temperature changes on large horizontal tanks. As a consequence of the new bearing system, the structures can be symmetrically founded showing that horizontal stresses are theoretically identical in both saddles. Moreover, due to the lever action of the rotating systems, the behavior of the structure under static and dynamic horizontal loads is greatly improved
