Latest Patents
Xiaochao Su holds a patent for a "Method and system for predicting corrosion fatigue life of prestressed concrete bridges." This invention discloses a method and a system that predicts the corrosion fatigue life of prestressed concrete bridges. The process involves predicting the corrosion level of the strand to obtain the residual tension force of a structure. A stress concentration factor is integrated to account for the stress concentration effect caused by pitting corrosion. Additionally, a growth model of the elastic stress of the strand under the coupled effects of corrosion and fatigue is proposed. A growth model of the plastic stress of the strand is established using a cross-section loss of the strand as a fatigue damage parameter, based on a degenerated elastic modulus of the concrete after fatigue. Failure criteria for the concrete, the strand, and a longitudinal tension bar are defined, forming a comprehensive set of methods for analyzing the life of a prestressed concrete bridge subjected to corrosive environments and fatigue loads. Xiaochao Su has 1 patent to his name.
