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, 313, 5A, 513, 5C, and 5D of this report for seismic loads, and Tables 3A, <br />36, 4A, 46, 5A, 56, 5C, 5D, 6, 7, 8A, 86, 9, 10, and 11 of this report for wind loads. <br />TABLE 3A—ALLOWABLE ADHESIVE BOND TENSION LOADS FOR THREADED RODS AND REINFORCING BARS IN THE FACE OF <br />GROUT -FILLED CONCRETE MASONRY UNITS (POUNDS)' 2,7,1,1,11,12,13 <br />Anchor <br />Spacing° <br />Edge Distances <br />Diameter <br />(inches), or <br />Embedment <br />inches <br />( ) <br />Load <br />Critical, <br />Minimum, <br />Reduction, <br />CriticalLoad <br />Minimum, <br />Load Reduction <br />Rebar Size <br />and sir <br />Scr <br />(inches) <br />sm;" <br />(inches) <br />Factor at s n; s <br />Ccr <br />(inches) <br />Cmin <br />(inches) <br />Factor at cm n6 <br />3/8 or No. 3 <br />33/8 <br />1240 <br />13.5 <br />4 <br />0.70 <br />12 <br />4 <br />0.80 <br />1/2 or No. 4 <br />41/2 <br />2035 <br />18 <br />4 <br />0.70 <br />20 <br />4 <br />0.76 <br />5/8 or No. 5 <br />55/8 <br />2840 <br />22.5 <br />4 <br />0.50 <br />20 <br />4 <br />0.71 <br />3/4 or No. 6 <br />63/4 <br />3810 <br />27 <br />4 <br />0.50 <br />20 <br />4 <br />0.66 <br />
