| Abstract: | A test about six external prestressed beams has been performed, a group of data about the deflection of the beams are got. Using the formula of the active code the deflection of the beams are calculated and another group of data of the beams are obtained. Then two groups of data are compared and the applicability of the formula of the active code is appraised. Finally some advice on how to develop a new and more accurate formula are presented. |
| Keywords: | external prestress concrete beam deflection second impact upper displacement |
