What is curtailment of flange plates is a plate girder?
5.0 CURTAILMENT OF FLANGE PLATES For a plate girder subjected to external loading, the maximum bending moment occurs at one section usually, e.g. when the plate girder is simply supported at the ends, and subjected to the uniformly distributed load, then, maximum bending moment occurs at the centre.
What is the function of flange in plate girder?
The main purpose of flange plates is to resist the bending moment acting on the girder. The top flange resists the bending moment by developing compression and the bottom flange resists the tensile force.
Why is gap provided between the web plate and flanges in riveted plate girder?
The resistance to bending and shear can be increased by increasing the distance between the flanges. The web plate which is thin is liable to buckle and to protect the thin web from buckling stiffeners are provided at supports and load points.
What is flange splice in plate girder?
When plate girders are longer the elements of their flanges, i.e., flange angles and flange plates may not be available in the required lengths so their splicing becomes necessary. A joint in the flange element provided to increase the length of the flange angle or plate is known as flange splice.
What does curtailment mean?
Let’s start with the basic definition of curtailment. According to the Merriam-Webster dictionary, the word itself means to “make less by or as if by cutting off or away some part.” In the context of a mortgage, you can make it less by paying off all or part of your mortgage loan ahead of schedule.
Where are bearing stiffeners used?
Bearing stiffeners are provided
- At the ends of plate girders.
- At the ends of plate girder and on both faces of the web.
- At the ends of plate girder and only on one face of the web.
- At the points of concentrated loads, to protect the web from the direct compressive loads.
What is a plate flange?
A plate flange is a flat, circular disc welded to a pipe’s end enabling the flange to be bolted to another pipe. It is often referred to as flat flange, plain flange and flange slip, etc. Two plate flanges can be bolted together with a gasket in between them, usually used in fuel and water pipelines.
What are the different modes of failures of a plate girder?
| Q. | The modes of failure of plate girder are |
|---|---|
| A. | by yielding of compression flange only |
| B. | by buckling of tension flange only |
| C. | by yielding of tension flange and buckling of compression flange |
| D. | by yielding of compression flange and buckling of tension flange |
What is a splice plate?
In construct, a splice plate is a thick metal sheet used used to reinforce the connection between structural steel beams. The joint between two pieces of steel is known as a splice, and each splice must be carefully reinforced to ensure a secure bond.
What is economical depth of plate girder?
The depth at which the weight of girder is minimum is its economical depth. If the depth of girder is less than 750mm, it is called shallow plate girder. If the depth is more than 750mm, it is called deep plate girder. ∴ Economical depth of a plate girder corresponds to minimum weight.
What is curtailment reinforcement?
Curtailment is a theoretical point where some of the reinforcement is cut off along the span of the beam where the bending moment reduces, given that the remaining reinforcement will be able to support the reduced bending moment. The steel is adjusted with respect to changes in bending moment over a section.
