Mechanical engineering foundation or foundation is a technical effort to get foundation type and dimensions of buildings that are efficient, so it can support the load and it worked fine. Engineering foundation is part of the geotechnical science.
Types of foundations
The foundation can be classified into three types:
The depth is relatively shallow entry to the ground, just a few feet into the ground entry. One type that is often used is the foundation of being a regular on the houses, made of concrete or masonry, carry the burden of the walls and columns of the building to the ground hard. In it consists of:
1. Local foundation
2. The foundation successor
3. The foundation plate
4. The foundation construction spider – profit
Used to distribute the burden of building through the weak soil layer at the top to the bottom layer of the harder ones. Examples include piling, pile, Kaison, and the like. That it can vary depending on the discipline , example: pile foundation
The combination of foundation and piling plates
Types of foundations used in building a plan depends on soil type and the load acting on the location of the project plan.
The foundation is designed to have a bearing capacity with reduced / limited settlement by geotechnical and structural engineers.
The main design consideration and the carrying capacity of land decreased, in some cases such as plaster, deflection / deflection foundation is also included in the consideration. When speaking of the decline, which is usually considered a reduction in total (overall the foundation down together) and differential decreased (most foundations are down / tilt). This can cause problems for structural supports.
Carrying capacity of the foundation is a combination of the friction force on the foundation soil (depending on soil type, density, cohesion adhesion values, depth, etc.), the strength of the foundation soil where it ends up, as well as the material foundation itself. The depth of the soil and the changes that occur in it is very difficult to ascertain, therefore geotechnical experts working load limit should only be, usually, a third of the power of design.
Load acting on the foundation can be projected to be:
1.Load horizontal / shear loads, such as loads due to soil compression force, load transfer due to wind forces on the wall.
2.Load vertical / compressive load and tensile load, for example:
Dead load, weight of sample alone building
Live load, occupant load instance, rain and snow
4.Force lift water
