摘 要: 本文采用子空间迭代法研究单、双向张弦梁结构的自振特性,然后进行参数分析。对前者,主要讨论了拉索截面面积、预拉力、整体倾角及斜撑杆的影响;对后者,主要讨论了拉索布置方式—折线形布索的影响等。得出的结论可供工程设计者参考。 By using subspace iteration method, the free vibration characteristics for one way and cross ways beam string structure (BSS) have been investigated respectively in this paper. Then the parametric analysis is carried out, including influences of different areas of cable, prestress, oblique angles and oblique robs on one way BSS , influence of a new layout of cable, i. e. , broken one on cross ways BSS. Conclusions obtained may be useful to designers.
