A master’s thesis was discussed at the College of Engineering at the University of Kerbala in the Department of Civil Engineering, tagged:
(Experimental study of composite columns under cyclic loads)
By researcher Zainab Fadel Kazem.
The research aims to study the behaviour of composite columns consisting of two outer and inner tubes well fixed together, and the space between them was filled with two types of concrete: high-strength concrete and the other with normal strength. The number of practical test samples represents 12 composite columns, six of which are square in section, the others are circular. The tested samples were subjected tp a lateral periodic force in addition to a vertical force with different values. The experimental results were compared with the numerical results obtained from the (ABACUS) program.
The results obtained through this thesis showed that the impact of high-strength concrete clearly enhanced the resistance performance of the composite columns to lateral loads. Regarding the effect of shape, the test results prove that samples with a circular section have greater strength to horizontal cyclic loads than samples with a square section under the same conditions.
The thesis was approved by the discussion committee, which consisted of Professor Dr. Ali Lafta Abbas from the College of Engineering, University of Diyala (chairman), Assistant Professor Dr. Zainab Muhammad Reda from the College of Engineering, University of Kerbala (member), and Dr. Kamal Darwish Ibrahim from the University of Kerbala, College of Engineering (member). Assistant Professor Dr. Bahaa Hussein Muhammad from the College of Engineering, University of Kerbala (member and supervisor), and Assistant Professor Dr. Ali Ghanem Abbas from the College of Engineering, University of Kerbala (member and supervisor).
