Prediction of Shear Capacity of UHPC–concrete Composite Structural Members Based on Existing Codes

Reinforced concrete (RC) structural members strengthened with ultrahigh-performance concrete (UHPC) have shown excellent performance in past experimental investigations. However, methods of predicting their capacity are currently very limited. This paper presents six independent methods of predicting the shear capacity of UHPC–concrete composite members based on the application of existing design codes. Three of these methods…
