摘要
通过建立不同截面形式(圆端形双肢、圆端形单肢、矩形)的钢管混凝土塔柱模型,施加偏压荷载,比较其受力性能。通过应力云图和特征截面的应力数值,可以反映后湖大桥所采用圆端形钢管混凝土双塔柱受力性能的优越性。
The models of concrete - filled steel tubular tower with different cross - section （circle - ended double - limb, circle- ended single- limb, rectangular） were established. By imposing eccentric compression, the mechanical behaviors were compared. By analyzing stress cloud and extracting the stress data of the characteristic section, the result reflects the advantages of the mechanical behaviors of the circle- end CFST with double - limb which was applied in Houhu Bridge.
