A flanged joint connection for connecting together by a bolted connection a pair of casing shells having connecting flanges (60, 74). The connection reduces bearing stress concentrations adjacent fillets (102, 106) provided at the junction of the flange (60, 74) and the casing shell surface (104, 108). A rectilinear edge portion (114, 116) is provided on a bolt head (118) or a spacer (120), or both, to avoid point contact of the bolt head (118) or spacer (120) and the flange face (90, 100) or fillet (120, 106). The rectilinear edge portion (114, 116) includes a convexly-curved surface (122, 124) that faces the fillet (102, 106). The incidence of cracks between a bolt hole (80) and the fillet (102, 106), as well as the incidence of circumferential cracks between adjacent bolt holes (80) is significantly reduced. <IMAGE> |
