| ABSTRACT:- The research shows the evaluation of the actual study of multi-story building in the University of Diyala by testing the ultrasonic pulse velocity and Schmidt hammer . The study has been conducted by investigating the results of two methods included ( 14 columns and 14 points by using three reading of pulse velocity and ten reading of Schmidt hammer test , for the building ).The results can be used for the evaluation of the pulse velocity readings between ( 3.4 – 5.0 km/sec ) and the Schmidt hammer test readings between ( 20 – 33). The comparison for the evaluation of building was made by three equations,(Based on Dr .Alsamerie,etc equation (1), Dr. Reof ,etc equation (2),and Dr. Isam ,etc equation (3) .The evaluation of results indicated that Eq. (1) gives higher compressive strength by (20.7 %) , and the Eq. (2) gives also higher compressive strength by (14.6%) when compared with Eq. (3). Therefore, the evaluation cant not used one equation ,but using more equations and take the average . we may get acceptable results for concrete strength .
