Term
|
Definition
| the stress developed by the force tending to produce movement or slippage at the interface between the concrete and the metal reinforcement bars. |
|
|
Term
|
Definition
| a connective joint between several distinct pieces. Typically an infilled concrete key between two prestressed hollow core pieces to connect the pieces in the case of shear forces. One connected with a shear key the pieces act as one piece or a slab. |
|
|
Term
|
Definition
| The length along a reinforced concrete beam that it takes for the beam to develop its full bearing capacity by achieving a solid bond between the reinforcing bar and the concrete. |
|
|
Term
|
Definition
| reinforcing bar that has been added to the compression side of a beam in order to keep the cross section smaller and increase the compressive strength (adding greater resistance to the internal moment of the beam) |
|
|
Term
| compression flange buckling |
|
Definition
| typical failure of a wide flange section. compression causes the top flange to buckle laterally. this can be stopped by reinforcing the compression flange. |
|
|
Term
| braced compression flange |
|
Definition
used to stop compression flange buckling, done by stiffening the compression flange laterally. one beam may cross above and be connected to the compression flange to prevent it from buckling.
the bottom picture on this page is an example

|
Term
| unbraced compression flange |
|
Definition
| a simple beam with a compression flange that has not been reinforced. controlling stress on the beam will be that which causes compression flange buckling. |
|
|
Term
|
Definition
typical failure of a wide flange section. compression causes the top flange to buckle laterally. this can be stopped by reinforcing the compression flange. The same as compression flange buckling.

Term
| Lateral moment of inertia |
|
Definition
| a measure of an object's resistance to changes in its rotation rate in the plane lateral to the material's primary axis. I plane in a wide section flange. |
|
|
Term
|
Definition
| rigidity of material in the weak direction. |
|
|
Term
|
Definition
| max allowable moment that can develop in a beam |
|
|
Term
|
Definition
| A hook shaped concrete reinforcing piece, at ends to resist |
|
|
Term
|
Definition
| A member that, when viewed in lateral section, is open. (wide section flange) |
|
|
Term
|
Definition
| a member that, when viewed in section, is closed. (box, hollow tube, world trade center, etc.) |
|
|
Term
|
Definition
| a horizontal member spanning between exterior columns. Typically supports the exterior wall in addition to a floor or roof. |
