Saddle pushing analysis in suspension bridge construction

Qi Dongchun,Wang Changjiang,Shen Ruli,Lin Qia

Strategic Study of CAE 2010, Volume 12, Issue 7, Pages 68-73

Abstract:

Some problems existing in saddle pushing, such as the pre-displacementprinciple, the relation of tower top displacement and tower bottom stress, the method of determining saddleThe reasonable model of saddle equilibrium condition and the pre-displacement calculation method areCombining with saddle pushing analysis of Baling River Bridge, the conclusion that the excess pushingThe cases following saddle pushing are the unfavorable conditions for main cables anti-sliding checking

Study on overall lifting program for steel box girder of large span of three-span continuous suspension bridge

Yao Qingtao,Pan Guilin,Yao Qingtao,He Chaoran

Strategic Study of CAE 2013, Volume 15, Issue 8, Pages 54-59

Abstract:

Unlike single-span suspension bridge,the three -span continuous suspension bridge is mainly characterized by slings set in both side spans, and the continuous transition of stiffening girders between the mid and side spans achieved by girders without slings in the main tower region, and usually restraint equipments set on the side span transition piers to achieve the coordinated deformation between the main cables and stiffening girders in the region, so the lifting method and key construction process for the stiffening girders of the type of suspension bridge is relatively complex. the Fourth Nanjing Yangtze River Bridge as the background, and according to the structural features of the large span three-span continuous suspension bridge, the reasonable lifting program is determined through the comparison and analysis on two different types of lifting sequence for steel box girders.
