Strand stress
Web15 Aug 2024 · However, the higher strand stress led to steeper slopes of lines in the transfer zone (24% and 55% steeper in dead and cut ends, respectively, in Fig. 11), resulting in unclear transfer lengths: increase in dead end by 11% and decrease in cut end by 17% from normal- to high-strength strand. This phenomenon can be reasonably addressed by … Web7 Dec 2024 · The strander works in tandem with the straightening and stress-relieving equipment and this assures a high degree of toughness and elasticity in the strand. The straighter the strand, the easier it is to place and tension, and less likely that it will become tangled on the job. What is stress concept in prestressed concrete?
