Research on Cumulative Damage of Reinforced Concrete Short Columns
Reinforced concrete columns are the main load-bearing elements in many structures and are also the elements that bear seismic effects when earthquakes occur. In high-rise buildings, bridges, and other building structures column members also gradually accumulate damage due to fatigue cyclic loading and gradually reduce their load-bearing performance. The design and fabrication of reinforced concrete column members, the application of equal amplitude cyclic loading to them, so that they enter different damage stages, the study of their fatigue damage after the fatigue damage of the load-bearing capacity, deformation capacity, and damage morphology and other damage, to reveal the fatigue damage on the shear performance of the members of the law of influence. The monotonic pushover and low circumferential fatigue proposed static tests of reinforced concrete columns were carried out to study the fatigue shear damage characteristics, damage mechanism, and mechanical properties of the member such as the bearing capacity after the damage. The test process is divided into two stages. In the first stage, a certain number of equal-amplitude cyclic loads are applied to the reinforced concrete column members to bring them to different degrees of damage, and the cumulative damage development law is studied. In the second stage, the members after the accumulated damage were subjected to damage tests under monotonic loading to study their residual bearing capacity and dimensional effects in the damaged state.
