预应力索—杆协同网架动力分析

The dynamic analysis of cooperative grids composed of pre-stressed cables and chord members

在研究分析了国内外预应力空间钢结构应用和发展的基础上,以一种下弦为预应力索的协同网架为构想,并对其协同工作的机理进行了进一步分析,给出了该协同网架的动力计算思路和方法,并通过该有限元计算方法对其受力规律进行了进一步研究。

Has analyzed the domestic and foreign pre-stressed space steel structure application and in the development foundation in the research, devised take one kind of last quarter as the pre-stressed cable cooperative grids, and carried on to its joint operation mechanism has further analyzed; produced should cooperative grids the power computation mentality and the method; and carried on through this finite element computational method to its stress rule has further studied.
