Analyzing Equilibrium and Redundancy of Indeterminate Structures

While analyzing any indeterminate structure using any method, it is necessary that the solution satisfy the following requirements: Equilibrium of the Structure Compatibility of the Structure Force Displacement Requirements

Definition and Types of Structures

Truss (Pin connected joints): A type of structure formed by members in triangular form, the resulting figure is called a truss. In truss joints are pin connected and loads are applied at joints. No shear force & bending moment are produced. Only axial compression and axial tension is to be determined while analyzing a truss. Structural Members: Those members that are

Tunnel Engineering | Methods of Tunneling and Hazards

Tunnel, passage, gallery, or roadway beneath the ground or underwater. Tunnels are used for highway traffic, railways, and subways; to transport water, sewage, oil, and gas; to divert rivers around dam sites while the dam is being built; and for military and civil-defense purposes. Subterranean galleries are a series of horizontal passageways on different levels, as in

Spillway - Definition, Types and Classification of Spillway

There are different types of spillways that can be provided depending on the suitability of site and other parameters. Generally a spillway consists of a control structure, a conveyance channel and a terminal structure, but the former two may be combined in the same for certain types. The more common types are briefly described below: Drop, Ogee, Siphon Chute,

Strain Hardening | Definition and Effects

In the plastic region, the true stress increases continuously i.e when a metal is strained beyond the yield point, more and more stress is required to produce additional plastic deformation and the metal seems to have become more stronger and more difficult to deform. This implies that the metal is becoming stronger as the strain increases. Hence, it is called "Strain

Sources and Types of Pozzolanic Material

A simple everyday definition of 'pozzolan' could be 'a finely powdered material which can be added to lime mortar (or to Portland cement mortar) to increase durability. A more formal definition is given by ASTMC618-84 as 'a siliceous or siliceous and aluminous material which, in itself, possesses little or no cementitious value but which will, in finely divided form in the

Soil Cement - Definition, Use in Earthfill Dams & Embankments

In recent years soil cement as a facing material for earthfill dams has been found economical where suitable riprap is not available near the site. A reasonably firm foundation is preferred so that deformation after placement of soil-cement is not significant; however, no unusual design features need be incorporated into the embankment. Normal embankment

Reverse or Ogee Curve - Definition and Making

Combination of two or more simple circular curves of different radius having their curvature in the same direction. Essentially, a compound curve consists of two curves that are joined at a point of tangency and are located on the same side of a common tangent. Though their radii are in the same direction, they are of different values. This is the process of establishing

Sand Trap Design Criteria & Location for Construction

Sand trap is a structure that is constructed to exclude the quantity of sand that is carried by water flowing in the channels or tunnels for power generation or irrigation or some other purposes. Sand trap is provided In the form of chambers that depends upon the discharge that is to be carried by the channel or tunnel. As it is general and true believe the life of dam

Definition and Types of Retaining Walls

A retaining wall is a structure that retains (holds back) any material (usually earth) and prevents it from sliding or eroding away. It is designed so that to resist the material pressure of the material that it is holding back. An earth retaining structure can be considered to have the following types: Gravity Walls Reinforced Gravity Walls Concrete Cantilever retaining wall Counter-fort / Buttressed retaining wall Precast concrete retaining wall Prestressed retaining wall

Residual Stresses - Definition, Properties and Effects

They have more surface exposure per unit volume, the flange tips tend to cool faster than flange-to-web junctures. Tension members response to load is much similar to that of tensile-test coupon . Member behavior may differ from coupon behavior because of: Residual stresses result principally from non-uniform cooling of hot rolled or welded shapes and

Ready Mixed Concrete - Definition and its Types

Ready mixed concrete production is a process, whereby, mixing and transportation of concrete is combining together and the product is delivered to the site, at the right time in the mould straight away. IS-4926, the definition of ready mixed concrete is: “Concrete delivered at site or in to the purchaser’s vehicle in a plastic condition and requiring no further treatment

Surveying Dictionary Words Definitions Starting from Q, R, S

Query: The process of selecting features in a database. Can be achieved through a query language directly on the data or, in a GIS, by interactively selecting features. Raasterization: The process that converts vector data, which is a series of points, lines and polygons into raster data which is a series of cells with a discrete value. Railroads: A category of rural transportation

Reasons to Keep Factor of Safety in Building Construction

Factor of Safety in buildings or other construction is kept so that to compensate any uncertainty in the design process. The uncertainty could come from anywhere in the design process including calculations, material strengths, environmental conditions, natural phenomenons, duty of the structure and last but not the least quality of materials used. Though there exist some
