10+ Crowe Horwath Interview Questions and Answers

The point where the shear force is zero is called the point of contraflexure.

• Point of contraflexure is the point where bending moment changes sign.

• It is the point where the bending moment is maximum.

• It occurs in a beam when the shear force changes sign.

• It is important to determine the point of contraflexure in order to design a beam that can withstand the loads applied to it.

Prestressed concrete is better than normal RCC due to its higher strength, durability, and reduced cracking.

• Prestressed concrete has higher strength and load-carrying capacity compared to normal reinforced concrete.

• It offers improved durability and resistance to environmental factors such as corrosion.

• Prestressed concrete reduces cracking and deflection under load, enhancing structural integrity.

• It allows for longer spans and thinner sections, resulting in cost savings and in...read more

The steel is placed in the SSB and cantilever beam to provide reinforcement and increase structural strength.

• Steel reinforcement is typically placed in the tension zone of the SSB and cantilever beam.

• The steel bars are positioned parallel to the axis of the beam to resist tensile forces.

• The placement of steel bars should follow the design specifications and structural engineering principles.

• In SSB, steel bars are commonly placed in the bottom half of the beam to counteract be...read more

PCC and RCC are different types of concrete used in construction.

• PCC stands for Plain Cement Concrete and is used for non-structural components like flooring, leveling, etc.

• RCC stands for Reinforced Cement Concrete and is used for structural components like beams, columns, slabs, etc.

• PCC does not contain any reinforcement while RCC has steel reinforcement to enhance its strength and durability.

• PCC has a lower strength compared to RCC.

• Example: PCC is commonly used for construc...read more

Creep, hogging, and sagging are terms used in engineering to describe different types of structural deformations.

• Creep refers to the gradual deformation of a material under a constant load over time.

• Hogging is a term used to describe the downward curvature of a beam or structure in the middle, caused by excessive load on the ends.

• Sagging is the opposite of hogging, where the beam or structure curves upward in the middle due to excessive load on the center.

• These terms are comm...read more

Drawing BMD and SFD of propped cantilever

• Identify the support and the point of loading

• Calculate the reactions at the support

• Draw the SFD by starting from one end and moving towards the other

• Draw the BMD by starting from the other end and moving towards the first

• Label the maximum and minimum values of SFD and BMD

• Check for equilibrium and consistency

M20 and Fe415 are grades of concrete and steel used in construction.

• M20 is a mix of concrete with a compressive strength of 20 N/mm² after 28 days of curing.

• Fe415 is a grade of steel with a yield strength of 415 N/mm².

• M20 is commonly used for residential construction while Fe415 is used for reinforcement in concrete structures.

• Both M20 and Fe415 are standardized by the Bureau of Indian Standards (BIS).
