FRAME STRUCTURE

A rigid frame structure is one made up of linear elements, typically beams & columns, which are connected to one another at there ends with joints that don’t allow any relative rotations to occur between the ends of the attached members, although themselves may rotate as unity. Continue Reading »

STRUCTURE

A structure is one in which the members are arranged in such a way that the weights, loads & forces are transmitted to the foundations by the cheapest means consistent with the intended use and nature of the structure.

There are two types of structures:

  1. Masonry Structures.
  2. Frame structure.

MASONRY STRUCTURE

In typical masonry construction, the main loads are transfer to the foundations via the internal load bearing wall. The external skin serves to provide weather protection and aesthetic quality. Continue Reading »

Local Coordinates and Global Coordinates in Finite Element Analysis

Local Coordinates

A local coordinates system whose origin is located within the element in order to simplify the algebraic manipulations in the derivation of the element matrix.

  • The use of natural coordinates in expressing approximate functions is advantageous because special integration formulas can often be applied to evaluate the integrals in the element matrix. Continue Reading »

How Canal Alignment should be done ?

Canal Alignment should be done in such a way that

  1. It should serve the entire area proposed to be irrigated.
  2. Cost of construction including cross drainage works should be minimized.
  3. A shorter length of canal ensures less loss of head due to friction and smaller loss of discharge due to seepage and evaporation, so that additional area may be brought under cultivation.
  4. A canal may be aligned as a contour canal, a side slope canal or a ridge canal according to the type of terrain and culturable area.
  5. A contour canal irrigate areas only on one side of the canal. Continue Reading »

Warabandi system of water management

MEANING OF WARABANDI

WARABANDI is a rotational method for equitable distribution of the available water in an irrigation system by turns fixed according to a predetermined schedule specifying year, day, time and duration of supply to each irrigator in proportion to the size of his landholding in the outlet command.

The term WARABANDI means turns (Wahr) which are fixed (bandi). Continue Reading »
