Prestress Beam Lab |
|
This mold and rebar was designed by an instructor for an |
|
experiment at SDSU. The purpose of this experiment is to |
|
teach students how rebar and prestressing effects the |
|
flexural capacity of a beam created with plaster of |
|
paris. The prestress molds for this lab have multiple |
|
locations the rebar can be located and prestressed. This |
|
will give the students more design freedom when creating |
|
their experiments and increase the variation of |
|
experiments between the groups. |
|
|
|
The three major changes the student can make to their |
|
beams is the location of rebar, the number of rebar used |
|
in the beam, and the size of the prestress force. Any |
|
single or combination of these changes can be made to the |
|
beams, it will be up to the students to decided which |
|
variables they want to investigate. |
|
|
|
The beams in the pictures were tested until failure and |
|
the beam with no rebar had a maximum load of 200 lbs and |
|
the beam with prestressed rebar had a maximum load of 350 |
|
lbs. |

More information on this lab and other labs will be |

available soon in the form of a lab manual from South |
