ESTIMATE FOR PLATE GIRDER

Dear Friends ,

Today we shall spend some time on the structural steel work.

We shall estimate the weight of a PLATE GIRDER today.

Plate girder is a built up section comprising of angles and plates.

1

The section of the Plate girder is as follows :

2

Now we shall find the weight of this Plate girder.

For ease of calculations , we shall assume that the span is only 1 m.

First step is to CODIFY each of the elements for better tracking.

3

let us just write down which section is to be used for each element.

4

Let us write down the numbers of each elements.

5

let us now write down the sizes of the individual elements.

6

Let us now write down the unit weights of the structural steel sections.

You can do this with the help of SP-06 or Steel tables.

7

Now we are in position to find out the weights of individual members .

8

Now we shall add up all the weights together .

This shall give us weight of the plate girder per running meter.
