CDM Smith Safety Engineer Interview Questions and Answers

BMD for sway frame is a diagram showing the variation of bending moment along the length of the frame.

• BMD for sway frame will have a shape similar to a zigzag pattern due to the presence of sway in the frame.

• The bending moment will be maximum at the points where the frame experiences maximum sway.

• The BMD can be drawn by analyzing the internal forces and moments acting on the frame.

The equipment sequence for any line bay starts with the circuit breaker and ends with the transformer.

• The circuit breaker is the first equipment in the sequence.

• Next comes the isolator switch.

• After that, the earth switch is operated.

• Then the line disconnector is opened.

• Finally, the transformer is disconnected from the line.

• The sequence is reversed when the line bay is put back into service.
