METHOD TO BUILD FRAMEWORK CONSTRUCTIONS |
摘要 |
Method to build space framework constructions with a triangular cross section designed above all for unstayed towers, stayed masts and as components in large power-line pylons. As frame girders you use a section of rolled steel having flanges which are plane and of equal size. The intermediate web connecting the flange edges is about twice as thick as the flanges. |
