Abstract

Traditional design of structural members considers less collision effects, so it may be possible to cause damage due to impact loads. In view of this, impact-resistant performance of the steel reinforced concrete beam with the rigid-flexible composite structure was analyzed based on the earlier research outcomes. In the numerical simulation of the process, the observed beams with four different measures including the unprotected, the rigid protective, the flexible protective and the proposed one were considered separately. Meanwhile, three considered constraint forms of the beam ends were as follows: fixed at both ends, hinged at both ends, fixed at one end and hinged at the other end. Protective effects of the different measures were evaluated by observing the strain, the displacement, the acceleration and the impact force of the target beam. Numerical results show that the proposed protective system works best. Moreover, the constraint forms of the structural components also have a significant impact on the protective effects.
