LOADING
Question
Which one of the following statements is NOT correct regarding gross section yielding?
A.
Generally, a tension member without bolt holes can resist loads up to the ultimate load without failure
B.
A tension member when subjected to an ultimate load will deform considerbly in the longitudinal direction
C.
A structure becomes more serviceable under the large deformation
D.
The IS code limits design strength by substituting a partial safety factor of 1.10 for failure in tension.
Answer ( Option C)

A structure becomes more serviceable under the large deformation

Solution

• As no reduction due to bolt holes, the tension member can resist load upto the ultimate load
• when subjected to ultimate load, there will be excessive deformation as the member would have already yielded.
• When large deformation is there, the structure becomes unserviceable
• Partial safety factor of 1.1 is considered in yielding.
• So, statement (c) is incorrect.
