Abstract:
To address the complexity and inefficiency of the current experimental and numerical simulation methods, a simplified analysis and prediction method for the dynamic response of fiber-reinforced polymer (FRP)/steel hybrid-reinforced concrete beams under impact loads was investigated. Firstly, a dynamic bending-shear resistance model of hybrid-reinforced concrete beams was established. Subsequently, based on this model and considering the stress wave propagation effect, an improved two degree of freedom simplified analytical model was proposed to predict the impact response of hybrid-reinforced concrete simply supported beams, and the accuracy of the model was verified. Finally, based on the dimensional analysis, an empirical prediction model of the peak displacement and impact force time history curves of the hybrid-reinforced beams was established by regression analysis of the results of 120 sets of impact conditions calculated with the two degree of freedom model. The results show that the prediction error of the model was basically within 20%, which provides an effective and simplified calculation method for the engineering practice of the hybrid-reinforced concrete simply supported beams under impact loads. © 2025 Chinese Vibration Engineering Society.
