#Is raft for windows 10 keygen#
The following are the major advantages of piled raft foundation, This ‘raft’ spreads the load imposed by a number of columns or walls over the area of foundation and can be considered to ‘float’ on the ground as a raft floats on water. In their normal form, raft foundations (sometimes referred to as mat foundations) are shallow foundations formed by a reinforced concrete slab of uniform thickness (typically 150-300 mm) covering a wide area, often the entire footprint of a building. In the case where the bearing capacity of soil is acceptable for the load imposed by structure deep foundation is generally used for prober stability of the structure. Wherever the bearing capacity of soil is acceptable for the load imposed by structure Shallow Foundation is taken into account. The main function of the foundation is to transfer a load of the structure to the soil beneath it which is capable of bearing that load.ĭepending on the type of soil beneath and the massiveness of structure shallow and deep foundation is preferred for construction.

To counter the problem of high load slab under the column is thickened in order to bear the load and ultimately providing safety. In cases of columns imposing more loads on the slab underneath, Plate Thickened under the Column Raft Foundation is used. Since reinforcement is provided in both directions foundation can provide resistance to moments in the respective directions. This factor provides the economical status to this Raft type.
It provides a thickness of about 300 mm to the slab hence used when the loads are relatively small. In it, both side mesh reinforcement is provided, adding to it the more reinforcement at joints are provided for stability purpose. In the Flat Plate type Raft Foundation, bending movement is in both directions. Similarly when the columns are well equally placed this type of raft foundation is used. After the examination, if the soil is showing the signs of Shear failure under loading raft foundation is one of an option.įollowing are the different raft foundation types,.The stress of soil will be another factor where raft foundation is taken into consideration(As I reduce the stress on the soil.).In the constructions where the task of waterproofing of substructure is to be rendered, mat foundation is adopted.If found to be constructed covers more than 60% of the total area of construction raft foundation is the most suitable one.If the water level is high in some subsequent areas where construction is to be carried out raft foundation is generally suggested by engineers.One of the necessary principles of adoption Raft or mat foundation is when the columns are closely placed and the load imposed is high by the structure.Raft or mat foundation is beneficial for the poor quality of soils on which foundation is to be laid.The Necessity Of Adopting Raft Foundationįollowing are the the necessities of Raft or Mat Foundation: Raft or mat foundation is suitable for weak soils hence if lesser stress is developed in the soil chances of shear failure decrease making soil suitable for bearing the structural load to an extent.In mat foundation, the wider area of footing is in the proximity of the soil as compared to other types of footing hence transferring the load over a larger area hence less stress is developed.The same is the reason for the even settlement of the soil hence ultimately the reason for the non-uneven settlement of the structure.Structure obtains high stability through this type of load transformation. As the definition of Raft or mat Foundation suggests, the footing is spread over a wider area taking load from numbers of columns and in turn, transferring the load evenly over the entire span of footing.10×10 Room Construction Cost Excel Sheet.Construction Material Testing Menu Toggle.30×40 House Plans | 1200 sq ft House Plan.
