Ramboll Assistant Design Engineer Interview Questions and Answers

Design of pier involves considering various factors such as load capacity, soil conditions, water level, and environmental impact.

• Determine the load capacity and type of pier required

• Analyze soil conditions and water level to determine foundation type

• Consider environmental impact and regulations

• Design for durability and maintenance

• Ensure safety measures are in place

Rigid pile caps are designed to transfer the load from the superstructure to the piles. The design should consider the pile arrangement, load distribution, and soil properties.

• The pile cap should be designed to distribute the load evenly to the piles.

• The pile arrangement should be considered to ensure that the pile cap is not overloaded.

• The soil properties should be analyzed to determine the bearing capacity of the pil...read more

Prestressing losses occur during the transfer of prestress from the jacks to the concrete. These losses can be divided into two stages.

• The first stage is immediate losses, which occur due to friction between the strands and the ducts, anchorage slip, and elastic shortening of the concrete.

• The second stage is time-dependent losses, which occur due to creep and shrinkage of the concrete, relaxation of the steel, and temp...read more

Design of steel members and connections involves determining the appropriate size and shape of steel components and how they are connected.

• Consider the loads and stresses that the steel members will be subjected to

• Select appropriate steel sections based on their strength and stiffness

• Design connections that can transfer loads between members without failure

• Ensure that the design complies with relevant codes and standar...read more

Pre-tension is applied before concrete is poured, while post-tension is applied after concrete has hardened.

• Pre-tension involves stretching steel cables or bars before pouring concrete to create tension in the concrete as it sets.

• Post-tension involves inserting steel cables or bars into hardened concrete and then tensioning them to create compression in the concrete.

• Pre-tension is typically used in precast concrete ele...read more

Analysis and design of piles involves determining the load capacity and selecting the appropriate type of pile for a given soil condition.

• Pile load capacity is determined through various methods such as static load tests, dynamic load tests, and pile integrity tests.

• Factors such as soil type, groundwater level, and seismic activity must be considered when selecting the type of pile.

• Common types of piles include driven ...read more
