DESIGN OF SHALLOW AND DEEP FOUNDATIONS FOR EARTHQUAKES

Although no charge or fee is required for using TeachEngineering curricular materials in your classroom, the lessons and activities often require material supplies. The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity. Most curricular materials in TeachEngineering are hierarchically organized; i. Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. Figure 1. The Tower of Pisa in Italy, a widely-recognized foundation failure.

Shallow Foundation and Deep Foundation

Those which transfer the loads to subsoil at a point near to the ground floor of the building such as strips and raft. A shallow foundation is a type of foundation which transfers building loads to the earth very near the surface, rather than to a subsurface layer or a range of depths as does a deep foundation. Shallow foundations include spread footing foundations, raft foundation known as mat-slab foundations, slab-on-grade foundations, strip foundations, buoyancy foundations, pad foundations, rubble trench foundations, and earth bag foundations. These foundation is according to BS : Shallow foundations are taken to be those where the depth below finished ground level is less than 3 m and include strip, pad and raft foundations.

In this video I have discussed about the difference between deep foundation and shallow domovstroitel. The main difference between shallow learning and deep learning architecture relates to the number of layers of artificial neurons used: shallow uses few ones comparatively to the deep learning. Figure Sliding action resisted by foundation. The transfer of loads from deep foundations to the soil is different from that of shallow foundations.

One such example of foundation failure involving toppling of apartment blocks due to liquefaction during the Niigata Earthquake is presented in Figure 1. Earthquake effects on shallow and deep foundations are accounted for by designing them structurally to provide necessary strength and ensure serviceability. Strength considerations essentially involves ensuring that the foundation loads remain well below that dictated by the allowable bearing capacity under seismic conditions and serviceability is ensured by designing the substructure for the estimated permanent ground deformation. Simple procedures for estimating bearing capacity and permanent ground deformation under earthquake conditions are presented in this note. Figure 1. Tilted apartment buildings 2. Any further increase in the amplitude of ground motion will lead to the failure of soil layer without any further increase in resistance.

In engineering, a foundation is the element of a structure which connects it to the ground, and transfers loads from the structure to the ground. Foundations are generally considered either shallow or deep. The design and the construction of a well-performing foundation must possess some basic requirements:. Buildings and structures have a long history of being built with wood in contact with the ground. Timber pilings were used on soft or wet ground even below stone or masonry walls. Perhaps the simplest foundation is the padstone, a single stone which both spreads the weight on the ground and raises the timber off the ground. Dry stone and stones laid in mortar to build foundations are common in many parts of the world.
