What is the difference between working stress approach and limit state approach?

For working stress approach, service loads are used in the whole design and the strength of material is not utilized in the full extent. In this method of design, stresses acting on structural members are calculated based on elastic method and they are designed not to exceed certain allowable values. In fact, the whole structure … Read more

What are Stresses in Soil, Over burden Pressure, Total Stress, Effective Stress, Pore water Pressure

The Structural loads are supported on soil through foundations. These loads produce stresses and resulting strains or deformations in the soil below the foundation. The deformation in the vertical direction is usually termed as settlement, which occurs due to the vertical stresses. Stresses in a Soil Mass The stresses which produce excessive deformations are termed … Read more
