Internal Connections (10 points) I have provided figures for connections #1 - #5. Your team only needs to figure out the types of internal connections for these connections. For Connection #6 - #10, I would like your team to find or produce the pictures and what types of internal connections they are. You can find the pictures on the internet (provide the source) or take them by yourself using your phone/camera. Connection # Figure Types of Internal Connections (Moment release, Shear Release, Axial Release, or Rigid) 1 Rigid Connection –
This connection supports the beam completely, by providing shear forces in both directions preventing the beam from translating parallel to the column. 2 Axial Connection - It provides axial forces that keep the beam from translating perpendicular to the columns surface. Additionally, it provides moments that keep the beam from rotating in any direction. 3 Rigid: This connection provides the forces and moments to fully constrain the beams (the welds in the joint) 4 Moment Release: This is a hinged release connection as it allows for rotation between the two bridge components, and they don’t carry moment. The connection has a possibility to carry shear and axial forces.
5 Pedestrian truss bridge in Georgia, USA Rigid Release - This connection provides the forces and moments to fully constrain the beams (the bolt in the joint) 6 Truss Bridge found on Internet Axial Release - It provides axial forces that keep the beam from translating perpendicular to the columns surface. Additionally, it provides moments that keep the beam from rotating in any direction. 7 Rigid - This connection provides the forces and moments to fully constrain the beams.
Bridge Joint found on Internet 8 Bridge Joint found on Internet Axial Release - It provides axial forces that keep the beam from translating perpendicular to the columns surface. Additionally, it provides moments that keep the beam from rotating in any direction. 9 Bridge Joint found on Internet
Rigid - This connection provides the forces and moments to fully constrain the beams. 10 Cable Bridge Joint found on Internet
Moment Release - This is a hinged release connection as it allows for rotation between the two bridge components, and they don’t carry moment. The connection has a possibility to carry shear and axial forces.

External Connections (Reaction Support) (10 points) I have provided figures for support #1 - #5. Your team only needs to figure out the types of external connections for these supports. For Support #6 - #10, I would like your team to find or produce the pictures and what type of supports they are. You can find the pictures from the internet (provide the source) or take by yourself using your phone/camera. Support # Figure Types of External Connections (Pin, Ball in Socket (3D pin), Fix, Roller/Rocker, Sliding Support, Bearing) 1 Pedestrian bridge in Gainesville Ball in Socket - This support has a support reaction at the ball and socket joint. There is a three-force reaction, and each force generates a moment. 2 Column support in airport, Taiwan Sliding Support –
This support moves the rollers(wheels) in between the two block supports. There are two force reactions with one of the forces producing a moment. 3 Support of Deception Pass, Washington Fix - This support restricts movement in every direction and rotation in every direction.
4 A tree on Cathedral Trail, Oregon Fix - This support restricts movement and rotation in all directions. 5 Roller/Rocker - This support restricts movement in one direction. 6 State Farm Arena Parking Lot, Atlanta Pin –
This support restricts movement in three directions and movement in two directions. 7 Grand Canyon Lookout View, Arizona Fix - This support restricts movement and rotation in all directions. 8 Sydney Harbor Bridge, Australia Pin - This support restricts movement in three directions and movement in two directions.
9 Random Bridge of the Internet Roller - This support restricts movement in one direction. 10 Random Scissor Pin - This support restricts movement in three directions and movement in two directions.
