, Table 6.6.1.2.3-1 and 6.8.2.2), inputs for connection eccentricity and the maximum length of longitudinal welds are required. Therefore, the effective area can be determined by the formula Aeff = (1-x/L)Agwhere x represents the connection eccentricity, L is the maximum length of the longitudinal welds and Ag denotes the gross area of the section. |
