Traditionally, bolt group coefficients are extracted by using tabulated values in the AISC Steel Construction Manual. However, these tables are limited to common bolt patterns, and specific load eccentricities and angles. Non-tabulated values must be extracted by using linear interpolation. This Maple Flow worksheet, however, calculates the bolt group coefficient for any bolt and load configuration by implementing the theory used to generate the tables. The results agree with those presented in AISC Manual of Steel Construction: Load and Resistance Factor Design, 2nd Edition.
