| Abstract | Foundations are installed in the buildings to transfer loads from the building to the underlying subsoil. In Yangon, two types of foundations are commonly used. Shallow foundation types are used for buildings with a certain height of up to four stories. However, when the buildings are tall or if the underlying soil is not strong enough to transfer the exerting loads to the subsoil, deep foundations may be the one to consider. Deep foundations of piles are installed beneath the structures to transfer building loads to the deep soil stratum. In a tall building that may be nine stories or more, larger diameter bored piles or drilled shafts should be installed up to a deeper stratum to transfer the exerting building loads. Therefore, these piles should be designed enough to carry loads from the structures to the subsoil within safe displacement limits according to the national building codes and standards. Instrumented pile load tests are done usually to check the loading capacity of piles. However, in some cases, piles load tests were failed with excessive settlements with bad skin friction. In such a case, the designer and developers have to revise the foundation plan by adding extra piles or pile length to the foundation plan and retesting the pile. Therefore, it may result in recurring costs and delay to the projects. For a city like Yangon where the underlying subsoil is not constant and not exposed to greater depth and no previous database of pile load tests, pile capacities in such soil could be harder to estimate for the high-rise buildings. Meanwhile, several pile load tests for tall buildings were done across the city within a decade. From these data, the best-fit design parameter for the pile foundation for tall buildings in Yangon can be obtained by interpreting these data, back calculations using various pile design methods with soil profile data, and 3D FEM simulations. Therefore, better pile design could be estimated for future pile design for tall buildings in the Yangon. |
