Sample interview questions: How do you approach the design of structures that need to withstand extreme temperatures or harsh environments?
Sample answer:
Design Considerations for Extreme Temperatures and Harsh Environments
1. Material Selection:
* Specify materials with high thermal resistance and low thermal expansion coefficients (e.g., steel, concrete, composites) for structures exposed to extreme heat.
* For cold environments, consider materials with high thermal conductivity to facilitate heat transfer and prevent freezing.
* Select corrosion-resistant materials (e.g., stainless steel, aluminum alloys) for harsh environments with exposure to chemicals or moisture.
2. Structural Configuration:
* Design structures with redundant load paths to minimize the risk of failure if a single component is damaged due to extreme temperatures.
* Create thermal breaks to prevent heat transfer between structural elements and sensitive components within the structure.
* Consider using insulated cladding or protective coatings to mitigate thermal stresses.
3. Load Analysis:
* Determine the anticipated range of temperature fluctuations and potential for thermal gradients.
* Calculate thermal stresses and deformations caused by these temperature variations.
* Account for potential environmental loads such as snow, wind, and seismic forces that may interact with thermal effects.
4. Joint Design:
* Select joint types that can accommodate thermal expansion and con… Read full answer
