Before taking up equilibrium conditions of a body, it is necessary to identify the various forces acting on it. The various forces acting on a body may be grouped into: (a) Applied Forces (b) Non-applied Forces (a) Applied Forces These are the forces applied externally to a body. Each of the forces is having contact…
There have been numerous government enquiries and subsequent reports over the last century into the construction of a tidal barrage across the River Severn Estuary linking England to Wales. None have come to fruition due to economic and environmental concerns and, the sheer magnitude of the project There have been many proposals and government white…
A freely suspended and properly balanced magnetic needle is expected to show magnetic meridian.However, local objects like electric wires and objects of steel attract magnetic needle towards themselves.Thus, needle is forced to show slightly different direction. This disturbance is called local attraction. The list of materials which cause local attraction are: (i) magnetic rock or iron ore, (ii) steel structures, iron…
Highway bridges have the main objective of carrying traffic; therefore traffic loading is a primary source of stress on the structure – quite often the largest one. However, traffic conditions are rather variable, as they depend on many factors, ranging from the macroscale (such as economic development) to the microscale (such as individual driver behaviour)….
In the present world, Infrastructural projects are booming at a very fast pace. For the speedy and safer execution of such projects like construction of roads and highways, vertical civil structures, there is a huge demand of geosynthetics. To counter these issues a number of ground improvement techniques and material are in practice. Geosynthetics have…
Amid thousands of homes in Texas that suffer damage from expansive clay soils and arguably improper structural and geotechnical design or Builders taking chances, this is just one case history that made it to the Texas Supreme Court. The following is by Wayne Slater of The Dallas Morning News (2007)….The house was constructed on what…
The term rdA may be called as moment of area, similar to moment of a force, and hence r 2 dA may be called as moment of area or the second moment of area. Thus, the moment of inertia of area is nothing but second moment of area. In fact, the term ‘second moment of…
All materials, including concrete expand or contract with the increase or decrease in temperatures. If suitable arrangements are not ensured for the expansion and contraction of concrete due to the temperature changes, cracks may occur. Concrete is not an elastic substance, and therefore it does not bend or stretch without failure. This concrete characteristic is…
Plastering Applying mortar coats on the surfaces of walls, columns, ceiling etc. to get smooth finish is termed as plastering. Mortar used for plastering may be lime mortar, cement mortar or lime-cement mortar. Lime mortar used shall have fat lime to sand ratio of 1 : 3 or 1 : 4. If hydraulic lime is used mix…
