Superior to conventional pre-stressed anchorage system, a new anchorage system design concept of cable-stayed bridge, the stress distributed transmitting anchorage system, is adopted to the Fourth Nanjing Yangtze River Bridge referencing to the design of conventional steel framed anchorage system. The conventional steel framed system relies on the back anchorage beam, which provides rigid bearing supports and results in large concentrated stress, and has certain risks on both structural and safety aspects. However, the stress distributed transmitting anchorage system is arranged with several rows of reinforced concrete tenon-joint shear connector (PBL) in anchoring area in order to transform the rigid bearing supports to flexible bearing supports which helps cable stress gradually delivering to concrete anchorage block, changes the pattern of stress distribution from concentrated to distributed, enlarges the stress region, decreases the degree of stress concentration, minimizes the structural risks, and provides plenty of emergency capacity by taking advantage of the ductility of PBL and allocating end bearing plates. The design concept of the new anchor system is briefly introduced in this paper.
