摘要
拉索损伤会引起拉索索力的变化和结构内力重新分布,主梁的挠度也将随之发生改变。文章以一个大跨斜拉桥为例,研究拉索损伤对斜拉桥结构性能的影响。
Damaged cable can cause cable tension and structural internal tension to transform,then the main beam deflection will also subsequently change.Based on a long-span cable-stayed bridge as an example,this dissertation studies that cable damage exerts an influence on the cable-stayed bridge.
