Abstract
Liquid Ammonia is stored under pressure in steel Horton spheres (diameter 17 m) under operating pressures of 5-6 kg/cm2. These spheres are supported on twelve steel columns, concrete pedestals, concrete ring beam and raft or pile foundation depending on the soil conditions. The continuous circular ring beam rests on 72 concrete piles each 45 mm dia and 17 to 20 m long. The second identical Horton sphere is supported on a raft foundation. The two Horton spheres have been subjected to a hydrostatic loading of 1. 7 kg/cm2 and an additional pressure of 7.3 kg/cm2 for performance check. Strains were measured at the crowns, four equatorial points and in six columns. The test results indicate that the spheres and the columns behaved consistent with theoretical values. The concrete in foundations was found to be of good quality corresponding to M20 grade. The settlements under four columns of the fully loaded actual structure were within anticipated limits i.e. 4-6 mm.

Health of Ammonia Horton Spheres and Foundations – A Case History
Liquid Ammonia is stored under pressure in steel Horton spheres (diameter 17 m) under operating pressures of 5-6 kg/cm2. These spheres are supported on twelve steel columns, concrete pedestals, concrete ring beam and raft or pile foundation depending on the soil conditions. The continuous circular ring beam rests on 72 concrete piles each 45 mm dia and 17 to 20 m long. The second identical Horton sphere is supported on a raft foundation. The two Horton spheres have been subjected to a hydrostatic loading of 1. 7 kg/cm2 and an additional pressure of 7.3 kg/cm2 for performance check. Strains were measured at the crowns, four equatorial points and in six columns. The test results indicate that the spheres and the columns behaved consistent with theoretical values. The concrete in foundations was found to be of good quality corresponding to M20 grade.
