McDermott International Civil Structural Designer Interview Questions and Answers

The type of weld used for connecting a column to a base plate is typically a fillet weld.

• Fillet welds are commonly used for connecting structural steel components.

• The size of the fillet weld is determined based on the forces and stresses the connection will experience.

• Proper welding procedures and inspections are essential to ensure the weld's quality and strength.

The top moment column to beam top side is typically welded on the compression side of the beam.

• Weld the top moment connection on the compression side of the beam for maximum strength.

• Ensure proper welding techniques and inspections are followed to maintain structural integrity.

• Consider using fillet welds or groove welds depending on the design requirements.

• Consult structural engineering codes and standards for specific welding requirements.

• Example: Weld the top moment connect...read more

The bolt to bolt distance depends on the specific design requirements and standards for the structural connection.

• The bolt to bolt distance is typically specified in the design drawings or calculations provided by the engineer.

• It is important to follow the recommended bolt to bolt distance to ensure the structural integrity of the connection.

• The bolt to bolt distance may vary depending on factors such as the size and type of bolts, the material being connected, and the load r...read more

Edge distance of 75mm is required to cover vertical reinforcement in all types of foundations.

• Edge distance is important to ensure proper anchorage and structural integrity of the reinforcement.

• In this case, a minimum edge distance of 75mm is specified for covering vertical reinforcement in all types of foundations.

• Examples of foundations where this requirement applies include spread footings, pile caps, and mat foundations.

Column to beam joints are typically connected using various methods such as welding, bolting, or using mechanical connectors.

• Common methods for connecting column to beam include welding, bolting, or using mechanical connectors

• Welding is a common method where the column and beam are fused together using heat

• Bolting involves using bolts to secure the column and beam together

• Mechanical connectors such as shear connectors or moment-resisting connections can also be used for joint...read more
