Alternative Endcut Designation, Introduction

Some characteristics of the endcut standards to be interfaced to AVEVA Marine are described below. The description does not claim to create any complete understanding of how this is organized, only to give some hints.

• The complete endcut information consists of one string that may become rather complex for endcuts with complicated geometry.

• This string specifies both the type and all the parameters that are separately specified in AVEVA Marine.

• Endcuts for built profiles are specified separately for web and flange (as though they were individual flat bars).

• The endcut string always starts by the endcut type that is a letter, for example, C.

• The rest of the endcut strings consists of a variable number of constituents, each preceded by a "flag" telling if the information that follows next is valid at the lower or upper edge of the profile (suppose a flat bar). (However, for certain types this flag may be embedded between one preceding and one trailing parameter). These flags are 'a' for lower edge, 'b' for upper.

• The information following each flag may be a number or one of another set of flags (on level two) identifying how to interpret the information that follows.

• If the secondary flag is missing the dimension given is interpreted as a distance along the edge that is used to produce an endcut with a non-right connection angle (or similar).

• Reserved secondary flags are for example, R for round notches, C for a sniped corner ("KS notch"),

• A couple of simple examples illustrate these principles:

• Ca45aR50 is a simple cutout of type 11 with an endcut angle that makes it extend 45 mm outside the nominal end point of the stiffener. The endcut has notch R50 in its lower corner (similar to the right endcut in the figure in paragraph 9.5 below).

• D15bS0 corresponds to the endcut 1302, 15.
