Assystem Interview Questions, Process, and Tips

Total vehicle load of class A and 70R loading.

• Class A vehicles have a maximum weight of 18,000 pounds

• 70R loading refers to a tire load rating of 7,000 pounds

• Total vehicle load would depend on the number of axles and tires on the vehicle

• Calculations can be done using the Federal Bridge Formula

Superstructure design methodology involves analyzing loads, selecting materials, and determining structural systems.

• Analyze loads and determine design criteria

• Select appropriate materials based on strength, durability, and cost

• Determine structural systems such as beams, columns, and trusses

• Consider factors such as seismic activity, wind loads, and temperature changes

• Use computer-aided design software to model and test ...read more

Governing criteria for substructure design

• Soil properties and bearing capacity

• Loads and forces acting on the substructure

• Environmental factors such as seismic activity and wind loads

• Building codes and regulations

• Construction materials and techniques

• Accessibility and maintenance requirements

The governing criteria for superstructure design include safety, durability, functionality, and aesthetics.

• Safety considerations include load capacity, wind resistance, and earthquake resistance.

• Durability considerations include corrosion resistance and maintenance requirements.

• Functionality considerations include the intended use of the structure and the needs of its occupants.

• Aesthetics considerations include the vis...read more
