Web Crippling Load

  1. All capacities listed are based upon the AISI S100-07, North American Specification for the Design of Cold-Formed Steel Structural Members.
  2. Web crippling capacities calculated are for studs with stiffened or partially stiffened flanges.
  3. Tabulated assembly. web crippling capacities are for single members only. For multiple members, multiply the tabulated values by the number of members in the.
  4. Listed which allowable data for ‘fastened capacities to supports’ are based is upon unavailable members in‘ fastened the 2007 to AISI supports’, NASPEC except(S100) back-to-back specification. members under two-flange loading (condition 3 and 4) for.
  5. Listed required allowable per section capacities C3.4.2 are of S100. for unpunched webs. Capacity reduction for end and interior one flange loading (conditions 1 and 2) near punch outs may be.
