www.hilti.comAllowable stress design information The load tables in this section were developed for use in NQA projects utilizing allowable stress anchorage design when appropriate per their design basis. The load values were developed based on testing per ACI 355.2 and ASTM E488. Additional information,

sites.esm.psu.eduIn beam design the normal stress obtained from maximum moment Mmax usually dominates over shear stress obtained from maximum shear Vmax (but for exceptions, see limitations below). Therefore, our first choice to obtain the section geometry is to use (1) where S is the so-called section modulus, c is the maximum value of y and the allowable stress

web.engr.uky.edu- Company design standards will dictate (e.g. Army allows a design unconfined compressive strength (q u) of 1.0 q u for "normal" traffic levels - less than 5 MGT/yr - and design of 0.8 q u when traffic levels exceed 5 MGT.) - Hay recommends factor of safety of 1.5 as applied to an ultimate bearing capacity of < 2.5 q u, thus allowable stress ...
