KC Cottrell Structural Design Engineer Interview Questions, Process, and Tips

Wind and seismic loads are considered as per IS codes in structural design.

• IS 875 (Part 3): Wind Loads

• IS 1893 (Part 1): Seismic Loads

• Wind loads are calculated based on the location and height of the building

• Seismic loads are calculated based on the seismic zone and soil type of the location

• The design should ensure that the structure can withstand the maximum wind and seismic loads as per the codes

Loads are applied to the structure in Staad model to simulate real-life conditions.

• Loads can be applied in different directions and magnitudes to different members and nodes.

• Types of loads include dead load, live load, wind load, seismic load, etc.

• Load combinations are used to consider multiple loads acting simultaneously.

• Load cases are used to analyze the structure under different loading scenarios.

• Examples of load ap...read more

Roark's formula is used for plate stress analysis in structural design engineering.

• Roark's formula is a mathematical equation used to calculate the stress and deflection of plates under various loads.

• It takes into account the material properties, plate geometry, and boundary conditions.

• Roark's formula is commonly used in the design of pressure vessels, aircraft structures, and other engineering applications.

• Examples of...read more

Manual stiffeners are designed to provide additional support to plate work.

• Manual stiffeners are typically used in areas where the plate work is subjected to high stress or load.

• The design of manual stiffeners involves determining the required thickness, length, and spacing of the stiffeners.

• The spacing of the stiffeners is typically determined by the plate thickness and the applied load.

• The thickness of the stiffeners...read more

ESP FGD Bag filters are used to remove particulate matter and sulfur dioxide from flue gas.

• ESP (Electrostatic Precipitator) removes particulate matter from flue gas using electrostatic forces.

• FGD (Flue Gas Desulfurization) removes sulfur dioxide from flue gas using chemical reactions.

• Bag filters are used to capture the particulate matter and sulfur dioxide that are not removed by ESP and FGD.

• The captured particulate ma...read more
