Portal frame structure can be built using Steel, Timber or Reinforced concrete.

• TRUE

• FALSE

The use of portal frame structure can create a wide span of building spaces without obstruction of intermediate columns

• TRUE

• FALSE

Portal frame consist of spanning members and supporting members connected with rigid connection.

• TRUE

• FALSE

Portal frame distributes bending moment stresses to the entire spanning members.

• TRUE

• FALSE

The use of portal frame will reduce bending moment at the mid-span of the beam thus resulting in smaller sized beam to be used.

• TRUE

• FALSE

Bending moment shown in the image is for ...

• Fixed portal frame

• Two pin portal frame

• Three pin portal frame

• Single pin portal frame

Referring to the bending moment diagram shown. Which of the following statements are TRUE?

• Maximum bending moment is shown at knee joint.

• Maximum bending moment is shown at the centre of spanning member.
