WebValues for joint efficiency ratings can vary fiom less than 10% for bonded joints to over 100% for fasteners. The smaller the effective load-bearing area of a joint, the greater is the joint efficiency. An integral fit joint can be designed with optimum Ioad- bearing area thus directly enhancing the joint efficiency. WebTests of bolted connector joints have shown that the load capacity of connections containing multiple fasteners in a row is not directly proportional to the number of fasteners, with those located near the ends of the row carrying a greater proportion of the applied load than those located in the interior of the row.
