Lahore, Dr. Zahid Ahmed siddique, Professor Department of Civil Engineering, University of Engineering and Technology, Lahore won the Prime Minister Award for conducting research on "Bond Strength of Model Steel and other steel".
Prof. Dr. Zahid Ahmed Siddique was also given the cash prize for the research work he completed in a record time. He conducted the study to evaluate the bond performance of model steel reinforcing bars. The study was carried out according to the AC1408.2R-92 pullout test6s which were conducted on fully automatic strain controlled universal testing machine of Shimazu, Japan. The data was recorded by the data acquisition system of a machine at every 50 millisecond.
The pullout samples were prepared with normal strength concrete having compressive strength of 30 MPa. The recorded slimp value was 85 mm. the embedded length was selected to be 12 d.
These pullout samples were put in a specially designed assembly to grip them in the testing machine. This assembly has the arrangement to eliminate any eccentricity during casting of the samples. The tests were conducted after 28 days.
State-of-the-art strain controlled fully computerized universal testing machine was used for the tests. The machine has its own data acquisition system. It recorded the data at every 50 millisecond time interval. Moreover being servo controlled, it also provided whole post peak bond behaviour which was not possible with the load controlled ordinary testing machine.UET Vice-Chancellor, Lt. Gen. (R) Muhammad Akram Khan and Teaching Staff Association congratulated the Prof. Dr. Zahid Ahmed Siddique on receiving this award.
