L&T Technology Services Civil Structural Engineer Interview Questions and Answers

A portal frame is a type of structural frame commonly used in buildings and bridges.

• Consists of vertical columns and horizontal beams connected together to form a rigid structure

• Provides lateral stability to the building or bridge

• Commonly used in industrial buildings, warehouses, and agricultural structures

Bar bending diagram shows the shape of a reinforced concrete bar after bending, while shear force diagram shows the variation of shear force along the length of a beam.

• Bar bending diagram displays the shape of a bar after bending to show the location and extent of bends.

• Shear force diagram shows the variation of shear force along the length of a beam, typically in a graphical form.

• Both diagrams are important in structu...read more

IS code refers to Indian Standard code used in structural engineering.

• IS 456:2000 - Code of practice for plain and reinforced concrete

• IS 800:2007 - General construction in steel

• IS 3370:1965 - Code of practice for concrete structures for storage of liquids

Effective length is a measure used in structural engineering to determine the stability and strength of a member.

• Effective length is the distance between points of zero moment in a structural member.

• It is used to calculate the buckling capacity of columns and beams.

• The effective length factor depends on the end conditions of the member.

• For example, a simply supported beam has an effective length factor of 1, while a fi...read more
