In cable-stayed bridges, especially asymmetric counterweights are always made to work together with cable pretension forces get a reasonable finished state. To solve the optimization problem of bridge considering counterweights, integrated method (IOM) for estimating and is proposed. this method, proposed act on anchor points. After that, summary minimum weighted total bending energy considered as two objective functions multiobjective problem. Finally, dynamic coefficient used realize...
To study the probabilistic distribution of maximum wheel unloading rate high-speed trains and its temporal correlation when a train passes over bridge, method for estimation extremal index is proposed. Using time series threshold theory, value cumulative function (CDF) regarded as derived validated. This approach can also address dependent series, which traditional probability formulas could not. Then, difference between treating independent investigated using Monte Carlo simulations....
The pylon of the Xinshougang Bridge, a welded steel box arch with variable cross-section, exhibits asymmetrical design and unevenly inclined limb ends. segmented assembly this uniquely shaped necessitates precise splicing. In paper, novel three-point method for segment attitude positioning is proposed based on local coordinate system. This facilitates accurate translation alignment between section preparation facility construction site. Furthermore, predictive methodology posture during...
Abstract Rapid construction of ripple web (RW) is a new technology that can be applied to the prestressed concrete (PC) box girder bridge with corrugated steel webs (CSWs). In order analyse mechanical behaviour in process when RW method applied, main Zhao-Jun Yellow River Super Large Bridge was adapted as engineering background, and three-dimensional simulation finite element model established. Thereafter, detailed analyses were carried out for CSWs, top bottom concrete, lining temporary...
