Structural Analysis of the Super Large Span Main Span Hybrid Cable-stayed BridgeChinese Full Text

SHAO Changyu ;TANG Hu ;DAI Changyuan;

Abstract: Theoretical derivations have demonstrated that for cable-stayed bridges, main beams spanning 0.3 to 0.32 times the span length at the mid-span generate half of the total axial force at the tower base. Based on this, a new type of hybrid beam cable-stayed bridge is proposed by replacing main beams within this range with lightweight beam types. Trial designs are conducted for a main span of 1 000 m with a combination of composite beams and conventional concrete composite bridge deck beams, as well... More
