It is possible that local strength of an HSS at the connection may control over member design. Therefore, the HSS wall thickness should be checked at the connection during member design.*

True
False

Variation in the stiffness of the HSS wall causes a non-uniform distribution of force through welds across the face of the wall.*

True
False

Blind bolt
Pre-tensioned through-bolt
Nelson stud
None of the above

CJP welds at tubes splices are encouraged and easy to produce.*

True
