Understanding Web Area andShear Resistance

Te effective web are a consides thee portion of thee web that actively contributes to shear resistance, accounting for openings, stigeners, and quirr modifications.

Kalkulating Effective Web Area

Te effective web area (A is 1; A is; A is 1; FLT: 0 is 3; Xi3; v effective 1; Xi1; FLT: 1 is 3; Xi3;) is calculated by y subtracting the e are of openengs andd consigning the e consignition of stigeners. The basic formula is:

A BEL1; BEL1; FLT: 0 BEL3; BEL3; v BEL1; BEL1; FLT: 1 BEL3; BEL3; = (d - t BEL1; BEL1; FLT: 2 BEL3; F BEL1; BEL1; FLT: 3 BEL3; BEL3;) × s

Kiedy:

  • d = web depth
  • t BEL1; BEL1; FLT: 0 BEL3; BEL3; f BEL1; BEL1; FLT: 1 BEL3; BEL3; = membrany of the flange or opening
  • s = spacing between stigeners or web segments

Standardy i Bezpieczne Faktory

Te standardy AISC są szczególne dla minimum web areas based on thee shear force and material properties. Inżynierowie must verif thate calculated effective web are a meets or exceeds these minimums to o ensure shear concity.

Dodatek

Opening such as holes for bolts reduce thee effective web area. The reduction is calculated by subtracting the are of thee openings from the total web area. Stiffens can increase shear capacity when conformity designed.
