245			_aGeneration of Optimal Load Paths for Corroded Reinforced Concrete Beams Part II: Multi-Angle Truss Model
300			_a115-126 p.
520			_aA multi-angle truss model is proposed based on the optimal load paths of corroded reinforced concrete (CRC) beams. The load paths of CRC beams at the ultimate limit state, considering various corrosion levels, shear span-depth ratios, stirrup ratios, and loading methods are first studied. The load paths incorporating multiple variable-inclination struts can realistically describe the force-transfer mechanisms of CRC beams under flexure-shear interaction. The limiting failure criteria of the proposed truss model are then presented to estimate the shear capacity of CRC beams. Finally, the proposed model is verified by comparing with the experimental results of uncorroded and corroded reinforced concrete (RC) beams. Results show that the proposed model can reasonably predict the shear capacity and failure mode of CRC beams. For CRC beams at the ultimate limit state, corrosion damage has a negligible influence on the trajectory of load paths.The load paths change with the increase of the shear span-depth ratios of CRC beams.
