Abstract:Experiments are presented for the welded seam performances of three kinds of imported Ctype fabric membranes. The influence factors of the weld seam strength are taken into account, such as the seam lap width,fabric property,temperature and moisture various conditions. Experimental data are listed in detail and evaluated comprehensively. And the ultimate tension,specimen fabrication,experimental procedures are also presented herein. It can be referred for the practical engineering design and specification.
Keywords:Ctype fabric membrane; welded seam; seam strength; membrane structure
