“…In addition to carrying axial loads, the structure also carries large lateral loads such as wind, earthquake, and other lateral loads that cause the columns to carry shear loads. Therefore the adequate shear capacity of the column must be calculated carefully [3].…”

This paper presents experimental results on the shear capacity of hollow reinforced concrete members without stirrups. The area of the hollow was 2.32% of the concrete cross-sectional area. The hollow size used in this study is smaller than the maximum percentage required in the code, where the maximum hollow area was 4% of the total cross-sectional area. The longitudinal reinforcement used in the specimen varies with the three types of reinforcement ratios. The test was carried out using the four-point shear test to achieve the expected shear failure mode. The loading was given monotonically until the specimen failed. Analytical flexural capacity was also calculated using the fiber element method. The specimens failed in shear failure mode, indicated by large diagonal cracks in the observed shear span. The influence of the hollow on the shear strength was also compared with the theoretical shear capacity proposed by the code. This comparison shows that the calculated theoretical shear capacity is conservative for hollow reinforced concrete structural elements with a hollow area smaller than 4%. The results of the flexural analysis show that all the specimens did not reach the flexural capacity due to premature shear failure.

“…Most of the research on reinforcement of concrete members is focused on rectangular cross sections [3]. However, circular cross sectional reinforced concrete elements are frequently used civil engineering construction, for instance, as columns in reinforced concrete buildings, as pile foundations, and bridge piers [4][5].…”

“…The shear capacity of circular cross sectional reinforced concrete elements is different from other cross sections. The circular cross sectional shear capacity of reinforced concrete structural elements has been investigated by several previous researchers before [3][4][5][6][7][8][9][10][11][12]. Thamrin et al [3] has developed an analytical prediction model that has been found to compare well with experimental results.…”

An experimental study of shear behaviour of reinforced concrete members with solid circular cross sections is presented. The test variables were ratio of longitudinal reinforcement and type of stirrups. The test was carried out on nine beams. Three beams were designed without stirrups, three with closed hoop stirrups, and the other with spiral stirrups. All tested beams were subjected to two-point monotonic loads. The test results showed that all beams without stirrups failed due to the shear force. Beams with hoop or spiral stirrups failed in flexural mode. The flexural capacity of beams with hoops and spiral stirrups was similar but the beams with spiral stirrups showed a slightly higher ductility. Analytical predictions showed that the chosen numerical model predicted the test result with good accuracy.

“…Similar to the studies conducted for rebar reinforced concrete members subjected to impact and residual capacity loading, the addition of rebar to the concrete column was able to improve the lateral capacity of the member. Thamrin et al conducted a study into the flexural capacity of reinforced concrete members and found that the overall flexural capacity was increased as the reinforcement ratio increased (Thamrin et al, 2017). This is due to how the steel rebar interacts with the concrete during lateral loading.…”

The Lateral and Post-Impact Residual Lateral Strength of Reinforced Concrete Columns

The nature of columns being the mechanism for transferring loading to the foundation of a structure positions it at ground level which makes the member susceptible to unexpected impact loadings in the form of vehicle collisions. These impacts will cause reductions in the lateral capacity which may or may not be sufficient for safely transferring the design loading. Lateral load resistance tests were conducted on 24 concrete columns with various reinforcement configurations and sizes of which, 13 were previously subjected to impact loading and were used to evaluate the post-impact performance and lateral load capacity retention. From these tests it was determined that the concrete-filled steel tube (CFST) specimens exhibited both the largest lateral and residual lateral capacities of 37.37 kN and 40.17 kN, respectively. The CFST member had the highest retention of lateral load capacity for both low and high-impact energy, retaining 75% and 107% of the baseline capacity of 37.37 kN for the unimpacted specimen, respectively.Increasing the specimen diameter had no discernible effect on lateral strength retention but reduced the residual deformation, especially at high-impact energies with the residual deformation being reduced by as much as 85% compared to the smaller specimen.I would like to thank my supervisor and mentor Dr. Hamzeh Hajiloo. Dr. Hajiloo provided a wealth of technical knowledge and unparalleled guidance and support through this process. Dr. Hajiloo assisted and guided me since I was an undergraduate and gave me the tools to succeed and excel in my graduate studies and future career. I gained a new perspective on education, research, forming relationships, and imparting my knowledge to others. Dr. Hajiloo always supported me, trusted my abilities, and most importantly believed in me before I had even applied for graduate studies. I could not have done this without him, and I will always be thankful to have had him as my mentor.I would next like to thank my colleagues at Carleton University who supported and aided me in this journey to complete my thesis. Jason Arnott, for always being there to help me or guide me in the conception, creation, and completion of my experimental study. Pierre Trudel, for always willing to lend a helping hand regardless of the amount of work to be done would manage to find the time to aid me with my study.I would like to thank Nipissing First Nation for the financial support through my graduate studies and my undergraduate degree. Without the support of my nation, I would not be where I am today and cannot begin to express the gratitude I have for allowing me to pursue higher education without having to burden myself with significant financial constraints.Finally, to my friends and family for their constant love and support over the past two years. Throughout this journey there inevitably was hard times and without the support of my friends and family, I may not have been able to make it to the end.
