Insufficient shear resistance exists at the supports of old prestressed hollow slab beams in expressway reconstruction and expansion. Three full‐scale reinforcement tests show the combined stiffening ring hoop ranks best with a 25.8% increase, followed by diagonal reinforcement at 19.9% and vertical reinforcement at 15%, each suitable for different ...

Split‐disk testing of precast ultra‐high performance fiber‐reinforced concrete tubes
Abstract Ultra‐high performance fiber‐reinforced concrete (UHPFRC) has great potential for structural applications involving precast cylindrical shapes, including pipes, silos and stay‐in‐place forms for concrete columns. This study examines the performance of UHPFRC rings under internal pressure simulated using the split‐disk loading method, along ...
