To ensure the main tower’s satisfactory status,it is necessary to analyze its structural response and its control measure. Thermal effects,shrinkage and creep effects also influence concrete main tower’s structural condition,so analysis of thermal effects,shrinkage and creep effects is essential.
处于悬索桥上部结构施工过程中的索塔所承受的荷载直接作用不断发生变化,尤其是索塔承受的中边跨主缆水平分力变化幅度较大,且对索塔结构安全影响很大,为保证索塔处于安全、完好的状态,有必要对索塔进行施工控制分析;而温度、混凝土收缩徐变等间接作用也会影响到混凝土索塔的结构反应,有必要对混凝土索塔的非荷载效应展开研究。
