Which one of the following is not the advantage of HSFG bolt?
Bolts are not subjected to shearing and bearing stresses.
The load transfer is by shearing stresses.
Less stress concentration.
No slip takes place in the joint.
Which one of the following is not limit state of serviceability?
Corrosion
Loss of stability
Fire
Vibration
Which one of the following is not an advantage of bolted connection over welded connection?
Connection can be made easily.
Accommodates minor discrepancies in dimensions.
Alterations in connections can be made easily in the field.
Making joint is noiseless.
Which one of the following is not a variable action?
Wind loads
Earthquake loads
Self-weight
Handling and erection loads
Which one of the following is not a type of bolt?
Turned bolt
High strength friction grip bolt
Hot rolled bolt
Black bolt
Which one of the following is not a correct statement about lug angle connection?
The connection of lug angle to main member shall preferably start in advance of the member to the gusset plate.
Minimum of two bolts are used for connecting lug angle to the gusset plate.
Maximum of five bolts should be used in the connection.
By using lug angle, there will be saving in gusset plate.
