| 摘 要： | 对自锚式和地锚式2种斜拉-悬索协作体系桥进行了成桥后的温度效应分析,分别考虑了体系温差、索梁塔温差、索塔日照、索梁日照4方面的影响,并对比了2种体系的结果.结果显示温度效应对2种体系内力和位移的影响都比较大,不同种类的温度效应对2种体系的影响程度也不相同,并对其原因进行了分析.

| Abstract: | As a new type of bridge,cable-stayed suspension bridge comprises with towers,girder,main cables,stayed-cables and hangers. It has merits of both suspension bridge and cable-stayed bridge,but its mechanical behavior is more complicated. In the design of these long-span bridges,the effect of thermal stress should be considered. This paper discussed the temperature effects on bridge structure after bridge finished when taking patterns of cable-stayed suspension as examples. One is a self-anchored bridge and th... |
