Welding requires a much greater level of skill than bolting. True or False

Welding is more suited to field conditions than bolting. True or False

Which of the following is generally less expensive and allows faster erection? Rigid Frame or Braced frame

Expert Solution

Solution:

First question:

Answer: True

Yes, Welding requires a much great level of skill than bolting.

Welding is done be skilled persons whereas bolting can be done be an unskilled labourer too if nuts and bolts are provided to him.

Second question:

Answer : False

For field conditions, bolting is more suited than welding.

In field conditions, there is a great chance of application of dynamic loading.

Welded connections cannot resist dynamic loading for longer period of time and so bolts and rivets ( in earlier days) are used for field conditions.

And also welding is generally done is workshops whereas bolting can be easily done at sites.

Therefore due to these reasons, welding is not more suited to field conditions than bolting.

Third question:

Answer: Braced frame

Braced frame is generally less expensive and allows faster erection.

A braced frame utilises less quantity of steel to produce more or less same strength as that of a rigid frame and hence is economical. And it is also easier to construct than rigid frames which allows for faster erection of braced frames.
