Impact-Resistant Analysis of Hinged Reinforced Concrete Beam with Composite Laminates

Under the impact loads, once the key load-bearing member is damaged, it will endanger the entire building structures. Hence, it is very important to study impact-resistant performance of structural members. In order to verify effectiveness of a new composite protective device proposed in the earlier time, a reinforced concrete beam hinged at both ends was choosen as the observed object. During the process of numerical simulation, the four different protective measures including the unprotected, the rigid, the flexible and the composite one were considered in sequence. Numerical results show that the proposed composite measure can achieve the best protective effect, and it may be considered as a new option for impact-resistant protection of structural memebers.
