WebIf necessary, holes except oversize or slotted holes may be enlarged to admit bolts, by moderate amount of reaming. Thread Length: When design is based on bolts with unthreaded shanks in the shear plane, appropriate measures shall be specified to ensure that, after allowing for tolerance, neither the threads nor the thread run-out be in the ... WebThe geometrical layout of the oversize hole joints is. shown in Fig. 2. The twelve joints with oversize holes were divided according to hole size into four groups of three joints. area to total bolt shear area (the A /A n. The ratio of net plate. ratio) was 0.68. The first group of three joints, designated OH1, had a hole
WebOversize or slotted holes do not affect losses in bolt tension with time. Slip behavior of these joints is similar to slip behavior of joints with holes of nominal size. The average slip coefficient for joints with 1/4 in. hole clearance was about the same as the slip coefficient … WebLecture 12.6: Fatigue Behaviour of Bolted Joints. SUMMARY: Non-conventional but practical situations occurring in bolted connections are discussed. The following problems are considered: ... The slip factor in slip resistant joints with oversize or slotted holes has to be reduced. In a joint, the step between adjacent surfaces may not exceed 2mm.
