| Summary |
So far, there are a number of pneumatic diaphragm structure built for the use as the roof of the large scale sport stadium or other facilities. However. in these kinds of structure they required a regular pneumatic compressor and the maintenance are complicate and costly. While.Hybrid cable structure is easy in maintenance and the cost is low. it's naturally becoming more and more well known to the world as ever.
In Hybrid cable structure, a powerful tensile stress is required and it is basically supported by the cable. The external load is mainly snow-load and it is structurally designed to be supported by the posts and the membrane. As a matter of fact, the top-part of the posts and in the frame's direction. the node should be in the form of "sliding node “and the analyzing should consider the sliding of the cable. However, in order to simplify the analysis we suggest and regard the sliding node as a fixed node. And in this research, we vary the effective elements (length of postsEnumber of the posts and rise ratio) of the structure for analyzing.
To compare the results between the sliding node and fixed node analyze and to draw a conclusion on the applicable of fixed node analyze to the sliding node analyze would be the main aim of this research
