<br />' When using the basic load combinations in accordance with IBC Section 1605.3.1, allowable loads must not be increased for wind or seismic loading.
<br />2 When using the alternative basic load combinations in the 2009 IBC Section 1605.3.2 that include wind or seismic loads, the allowable loads for anchors may
<br />be increased by the tabulated factors found in the right half of the table. Alternatively, the alternate basic load combinations may be reduced by multiplying them
<br />by the reduction factors found in the left half of the table. For example, for stainless steel rods in shear, the alternate basic loads for wind or seismic may be
<br />multiplied by 0.87 for shear loading or divided by 1.14 (1/1.14 = 0.87), as applicable. For the 2018, 2015, 2012 IBC, the allowable loads or load combinations
<br />must not be adjusted.
<br />3 The above modification factors are applicable under the 2009 IBC only, for Tables 3A, 36, 5A, 513, 5C, and 5D of this report for seismic loads, and Tables 3A,
<br />313, 4A, 413, 5A, 513, 5C, 5D, 6, 7, 8A, 813, 9, 10, and 11 of this report for wind loads.
