Cable Stayed Bridges

There exist evident shear-lag phenomena in large-span composite cable-stayed bridges under the action of axial force, especially in the deck with double main girders. In order to discuss the distribution law of the effective flange width coefficient along the span, caused by axial force, finite element computations of five composite cable-stayed bridges and theoretical analysis have been performed. The transmission angle of axial force caused by the axial compression of stay cables was given, meanwhile the formulas for computation effective slab width coefficient under axial force were suggested.

<p>Recent trends towards performance-based fire designs for complex and critical structures have posed questions about the fire resilience of bridge infrastructure. There are little-to-no code requirements for bridge fire resistance and practitioner guidance on the subject is limited. Research on the fire performance of cable-supported bridge structures is scarce and knowledge gaps persist that inhibit more informed fire protection designs in a variety of bridge types. There have been few numerical or experimental studies that investigate the fire performance of steel stay-cables for use in cable-supported bridges. The thermal response of these members is critical as cable systems are highly dependent on the response of individual members, such as in the case of an anchor cable for example. The study herein examines the thermal response of several varieties of unloaded steel- stay cable during exposure to a non-standard methanol pool fire and the implications for the structural response of a cable-supported bridge. Experimental thermal strain data from fire tests of various stay-cables is used to inform high-level insights for the global response of a cable-supported bridge. Namely, the effects of cable thermal expansion on the overall cable system is approximated.</p>

<p>Taking the partial cable-stayed bridge with main span of 248 meters which used on the railway coal corridor from western Inner Mongolia to central China as an example. the adaptability and particularity of partial cable-stayed bridge in the span range are analyzed based on structural static analysis theory. Pylon and girder rigid fixity, pier and beam separation system is applied, H- shaped bridge towers, the double cell concrete box girder and the monofilament epoxy coating prestress strand is used in this bridge. The results indicate that stay-cables contribution to the overall stiffness value of 33%. In order to improve the structure performance of the controlling area such as cross section, bridge tower adopt the high tower type system, depth-span ratio is determined to be 1/4.35, C60 high performance concrete is applied. The main pier bearing adopts double 190000 kN large tonnage steel spherical bearings because of the heavy dead loads and the heavy live loads, using the high-performance materials and Partial sealing technique to ensure the bearing durability, stability and long service life. The structure of the bridge meets the requirements of heavy haul railway according to the analysis.</p>
