This Spreadsheet is intended to help practising engineers to quickly optimise pad foundations. Pad foundations are generally shallow foundations, but can be deep depending on the ground conditions. They are a form of spread foundation formed by rectangular, square, or sometimes circular concrete ‘pads’ that support localised single-point loads such as structural columns, groups of …
The estimation of pile load capacity and settlement under a load is based on the results of field investigations, laboratory testing and the empirical and semi-empirical methods. These estimated values should then be confirmed by field pile load tests. Pile load tests, in practice, are normally executed in two alternative ways: 1. Test Pile Preliminary …
Barrette pile is a type of drilled and cast-in-place pile, the distinctive characters of which are the shape and way of drilling. Grab-bucket or Hydrofraise type drilling tools are used for barrette pile construction. The size of these tools determines that of the piles. The simplest piles are made with one stroke of a …
This is dependable foundation and is used in those place where the load of the structure is pretty and bearing capacity of soil comparatively poor. The grillage foundation helps in distributing the load over a wider area of subsoil. The grillage foundation helps in avoiding deep excavations as the necessary base area is provided for …
Object of FoundationAs started earlier, the foundation is the device of transmitting the load of the whole structure to the sub-soil beneath it. However the following are the objects of providing foundation.1. The aim of foundation is to distribute the load of the structure over a large area or to transmit the load to the …
