Frequently Asked Questions

Q1: What is structural design?

A1: In a construction process and engineer’s environment, determination of entire proportion and dimension of the supporting framework along with selection of individual members is called Structural designing. An engineer in this field is responsible for the structural design within the constraints imposed by the architect.

Q2: What are the different types of loads?

A2: Different types of loads are given the below table

Types of loads Examples
Dead loads Suspended ceiling, floor covering, partitions – these are all permanent
Live loads Furniture, occupants of building, equipments – these are not permanent
Wind Loads Pressure on exterior of a building
Snow loads Differs with geographical location and drift
Earthquake loads Horizontal forces causing ground motions
Other loads Soil and hydrostatic pressure

Q3: What is steel and its properties?

A3: An alloy of primary iron, carbon and a small amount of other components like nickel, manganese etc is called Steel. Though carbon contributes to its strength, it reduces ductility of the steel. Properties of steel are

  • Ultimate stress
  • Yield stress
  • Percent elongation
  • Coefficient of thermal expansion
  • Modulus of elasticity

Q4: What is structural steel and its types?

A4: A material utilized for steel construction that is formed with a particular shape following specific standards of chemical composition and strength is known as Structural Steel. They are also called hot rolled products. There is a high demand for structural steel for construction purposes these days. Types of structural steel are Steel beams, steel channels, steel angle, steel flats.

Q5: What are advantages and disadvantages of structural steel?

A5: Advantages and disadvantages of Structural Steel are

Advantages Disadvantages
Great strength, light weight, easy of use, uniformity Buckling
Elasticity Maintenance cost
Toughness Fire proofing cost
Ductility Fatigue
Additions to existing structures Brittle fracture

Q6: What is a bolt?

A6: A metal pin with two ends where head is at one end and a shank threaded at the other end to receive a nut. Steel washers provided under nut as well as bolt serve mainly two purposes,

  • To prevent the threaded portion from bearing on connecting pieces
  • To equally distribute the clamping pressure on the bolted member
