弦支叉筒网壳结构性能分析及模型制作

Analysis and Modeling of Suspen Latticed Intersected Cylindrical Shell Structural Performance

文章首先介绍了一种新型大跨空间结构--弦支叉筒网壳,弦支叉筒网壳是在传统的叉筒网壳基础上,将造型独特、受力性能良好的刚性叉筒网壳与柔性索杆体系结合,形成一种刚柔性组合空间结构。文章以投影为正六边形的弦支叉筒结构为代表,结合实物模型分析了该结构的特点,运用ANSYS对计算模型进行预应力设计和静力性能分析,并设计制作了若干缩尺模型,验证了该体系的可行性与合理性。

This paper introduced a new type of large span structures-- suspen latticed intersected cylindrical shell,which combines rigid intersected cylindrical shell with flexible cable-strut system.We chose the regular hexagon suspen latticed intersected cylindrical shell as a representative to conducts the design of prestressed model and static performance analysis by ANSYS software.At the end of all,we made series of models to verify the feasibility and rationality of the system.
