(a) The tabulated values are design values for the normal duration of load. All values shall be permitted to be adjusted for other load durations provided that the adjusted reaction design value is not greater than the value specified below. Bearing stiffeners shall be installed in accordance with the recommendations provided by the manufacturer and APA D710.

(b) The allowable reaction design capacity interpolated in accordance with footnotes (c) and (d) as necessary and multiplied by an applicable load duration factor.

(c) Interpolation of the intermediate reaction between 3.5” and 5.5” bearing lengths is permitted. 

(d) Interpolation of the end reaction between 1.75” and 4” bearing lengths is permitted.
