摘　　要：拉索人行桥是一种新型结构,具有精巧的造型和显著的经济性。由于需要考虑预应力和几何非线性的影响,从而给这种结构的分析增加了难度。对拉索人行桥结构的静力与动力特性分析进行了研究,并采用能量变分原理进行了求解。通过一个算例说明了其应用。As a new structural type,the cable footbridge makes itself promising by its elegant shape and prominent economical characteristics.Because of the influence of prestress and geometrical nonlinearity,there are many difficulties in the analysis of this structure.In this paper,the static and dynamic characteristic analysis of the cable footbridge structure is discussed and solved by the energy variational principl.A numerical example is also given for referance in practical design.
