Abstract

As the stay cables are the key members of large span cable-stayed bridges, Accurate calculation of its bearing capacity is the basic foundation of structure design and soundness assessment. Using the statistical theory, 81 7-1770MPa new wire strength test results are employed to investigate the law of wire tensile strength distribution. Based on this, the cable parallel system and Monte Carlo sampling method are adopted to develop the Daniels model based bearing capacity calculation theory of parallel wire cable. Using this model, the general law between cable bearing capacity and wire number in it is investigated further. The research indicates that the tensile strength of single short wire follows the normal distribution. And the tensile strength decreases with the increase of the wire length. The whole bearing capacity per single wire also decreases with the increase of wire number in the cables.
