Evaluation of Residual Lateral Capacities of Impact-Damaged Reinforced Concrete Members

To study the residual lateral capacity of reinforced concrete (RC) columns after being subjected to static and horizontal impact action, tests a total sixteen RC were conducted. The variables considered in included shear-span ratio, weight velocity. experimental results, including force, deflection strain, as well cracking pattern failure mode, discussed. Compared with load–deflection curves under loading, it can be found that inertial effect plays significant part dynamic behaviour columns. Subsequently, six specimens slight damage carried out obtain their performance. Based on Park–Ang model is widely used for assessing post-seismic performance members, an evaluation method structural loading was developed, its accuracy confirmed by results.
