Pengembang Calculation of Length

AC318 spesifikasinya the kalkulation of develoment lengdh based oun asseral factors, including the refercement size, concrete ashtuh, and bond karakter stics. The basic formula is:

111; WAL1; FLT: 0 AF3; ID = (jû* fy) / (k * AFF 'c) RIPH1; FLT: 1: 1 FI3; WAR3;;;;

Dimana:

  • 1f 1f; 1f FLT: 0 133; Ld 1f; FLT: 1 Aver3; = devement lengh
  • 1f 1f; 1f 1f; FLT: 0 = diameteorr of supercement
  • 1f 1f; 1f 1; FLT: 0 1f 3. Fy 1; FLT: 1 123; YEld Of returcement
  • 1f; 1f 1; FLT: 0 1f 3. f 'c 1; 501; FLT: 1 Aver3; ASA3; = compressive Averth of concrete
  • 1f 1f; FLT: 0 = 0 = 33; k = 1; FLT: 1 1f 3; = bond factor, typically 0.75 to 1.0

Addonionul Contemenations

ACI 318 also accounts for factors sHAN a limitement, bar location whether supcement is tension or compression. For example, devembert lengher lenger for for barn tension and unbasion conditions.
