摘    要:随着苏通大桥的通车以及香港昂船洲大桥的建设,已步入千米级斜拉桥建设的新纪元;因此研究千米级斜拉桥的非线性影响对以后类似桥梁的设计建设有非常重要的意义。分析汽车荷载作用下千米级斜拉桥的静力非线性响应,得出了斜拉桥主梁、主塔和拉索这三个不同构件汽车荷载作用下非线性静力响应的大小;并进一步分析了跨度增大对非线性响应的影响。

关 键 词:斜拉桥  千米级  非线性  汽车荷载

Abstract:With the commissioning of Su Tong Bridge as well as the construction of Stonecutters Bridge of Hong Kong, we have entered a new era of construction of kilometer class cable stayed bridge; so it is of very important significance for the future design and construction to research on the nonlinearity of kilometer class cable stayed bridge. This paper analyzes the static non linear response of the kilometer class cable stayed bridge under the auto load and obtains the non linear static response size of the main tower, the girder and the cable; this paper also analyzes the non linear response effects with increasing spans.
Keywords:cable stayed bridge    kilometer class    nonlinearity    auto load
