McDermott International Associate Engineer Interview Questions and Answers

Design steps for creating a steel composite girder and structural detailing

• 1. Determine the required load capacity and span of the girder

• 2. Select appropriate steel and concrete materials for the composite girder

• 3. Develop a structural analysis model to ensure the girder meets design requirements

• 4. Design the steel section of the girder including flange and web dimensions

• 5. Determine the shear connectors and their spac...read more

Buckling analysis for steel arches involves determining the critical load at which the arch will buckle under compression.

• Calculate the critical load using Euler's formula: P_critical = (pi^2 * E * I) / (K * L)^2

• Consider factors such as material properties, geometry, and boundary conditions in the analysis

• Use software like ANSYS or ABAQUS for finite element analysis to simulate buckling behavior

• Perform sensitivity anal...read more

A thrust block is a concrete block used to resist the thrust of a pipeline or conduit.

• It is used to prevent the movement of a pipeline or conduit caused by internal pressure.

• It is typically made of concrete and is designed to withstand the force of the fluid or gas flowing through the pipeline.

• Thrust blocks are commonly used in water and sewage systems, as well as in oil and gas pipelines.

• They are usually installed at ...read more

Pipe bedding details are designed to provide support and stability to the pipe.

• Determine the type of soil and its load-bearing capacity

• Select the appropriate bedding material, such as crushed stone or sand

• Ensure proper compaction of the bedding material

• Design the trench width and depth to accommodate the pipe and bedding

• Consider factors such as traffic loads and environmental conditions

• Follow local codes and regulation...read more

A non-restrained joint is a joint that is free to move in all directions.

• A non-restrained joint allows for movement in all directions without any external force or constraint.

• Examples include ball and socket joints in the human body and expansion joints in buildings.

• Non-restrained joints require careful design and consideration to ensure proper function and stability.

• In engineering, non-restrained joints are often used...read more
