Which of the following are characteristics of a continuous span? correct answers - Span deflects
downward when loaded, causing rotation at the supports
- Span may deflect upward if adjacent span has more load
- shear forces maximum at supports
- positive moment greatest at or near midspan
- negative moment greatest at intermediate supports
Which of the following are characteristics of a cantilever span? correct answers - span deflects
downward when loaded, with no rotation at the support
- shear forces maximum at support
- maximum moment greatest at support
- shear connectors tie the deck and superstructure together
- beams act independently of the deck
- deck helps the top flanges carry the load correct answers - composite
- non-composite
- composite
the additional inspection requirements for fracture critical bridges were in response to the failure
of what bridge? correct answers Mianus River Bridge
the following information must be included in a bridge database correct answers
3 bridge components correct answers deck, superstructure, substructure
, which of the following conditions describes a component with minor deterioration, section loss,
spalling or cracking? correct answers fair
