A flush collar is identical in function to the lapped collar but requires neat fit of all dimensions. A flush collar is appropriate in a high shear environment where the eccentricity resulting
9、 from the lapped joint is unsatisfactory. This situation frequently arises when a stanchion is termi- nated on a bulkhead (see figure 11). 3.1.10 Intermediate lateral support (ILS). ILS members are used to stabi- lize long, unsupported spans of beam-plate combinations. Three approved means of provid
10、ing ILS are: (a) (b) ILS cut from plate (see figure 14). (c) Rolled shape ILS with web inserts to stabilize the flange (see figure 13). In-line bracket ILS (appropriate only if plating exceeds 30.6 pounds (0.75 inch) (see figure 6). 3.1.11 Hull pad. A hull pad is used when a rolled shape terminates
11、abruptly at a piece of plating. This detail is not considered to be recom- -. mended practice (see figure 12). 3.1.12 Stanchion details. Stanchion details are classified according to the type of stanchion member (that is, wide flange members versus structural tube) and continuity of the stanchion (t
12、hat is, terminating or continuing). For further guidance on the design of stanchion details see section 3.6. 3.1.13 Flange inserts. Flange inserts are used to increase the landing area for certain stanchion details. See section 3.6 for further design guidance. 3.1.14 Web inserts. Web inserts are use
13、d at the intersection of two members whose webs are perpendicular. They support the flange of the deeper of the two intersecting members. 3.1.15 Cutouts. Cutouts must be provided whenever a structural member pierces another member or plate. The dimensions of a cutout are strictly a function of the c
14、ross-sectional properties of the piercing beam. 3.1.16 Snipes. Snipes are small cuts on corners of individual pieces to permit fit-up. Straight snipes are shown but semicircular ones are also used. 3.2 Definition of nomenclature for variables. Throughout this handbook, upper and lower case variables
15、 are used to distinguish between information derived within a set of algorithms and information input to a set of algorithms. Similarly, conventions regarding subscripts have been defined to provide consis- tency among similar details. These definitions and conventions are presented in appendix A. A

If the stanchion inter- section does not occur at the intersection of two T-section members, then the flange of the T-section must be supported by an in-line bracket. For heavy tube st
