Deputy Structure Manager Interview Questions and Answers

Grade 8.8 bolt refers to its material strength and hardness.

• The first '8' refers to the material strength measured in tensile strength in MPa.

• The second '0.8' refers to the material hardness measured in the ratio of yield stress to tensile strength.

• Grade 8.8 bolts are commonly used in construction and engineering applications.

• Other grades of bolts include 4.6, 5.6, 6.8, 9.8, and 10.9, each with their own material strength and hardness ratings.

Criteria for designing steel beams include load capacity, span length, deflection limits, and material properties.

• Load capacity must be determined based on the expected loads and the strength of the steel.

• Span length affects the size and shape of the beam, as longer spans require thicker and wider beams.

• Deflection limits must be considered to ensure the beam does not bend or sag too much under load.

• Material properties such as yield strength, modulus of elasticity, and ductili...read more

Girders are used instead of slabs for higher spanned bridges due to their superior load-bearing capacity and flexibility.

• Girders have a higher load-bearing capacity compared to slabs, making them suitable for longer spans.

• Girders provide flexibility in design, allowing for various bridge configurations and accommodating different types of loads.

• Girders can be precast or cast-in-place, offering construction efficiency and cost-effectiveness.

• Examples of girder bridges include b...read more

Rolled, welded and hollow sections are applicable in structural engineering for various purposes.

• Rolled sections are commonly used for beams and columns in buildings and bridges.

• Welded sections are used for structures that require complex shapes or sizes that cannot be achieved with rolled sections.

• Hollow sections are used for structures that require high strength-to-weight ratios, such as towers and offshore structures.

• All three types of sections have their own advantages an...read more

IRC 6 loads are the standard loads specified for the design of bridges in India.

• IRC 6 loads are specified by the Indian Road Congress (IRC) for different types of vehicles and their loads.

• These loads include the weight of the vehicles, impact factors, and dynamic loads.

• IRC 6 loads are used to determine the maximum load that a bridge may experience during its design life.

• Examples of IRC 6 loads include the standard axle loads for different types of vehicles, such as cars, truc...read more
