Setting the Project to FRP Mode

Basic customizable FRP settings can be defined via the hull utility program Inithull. The function requires an input file written in TIL format described later in this text. The settings are stored in the OGDB data bank in an object with the fixed name __SBH_GRP_OBJECT__. This object is required if SBH_GRP is set (see below).

The setting of the environment variable SBH_GRP controls whether FRP is enabled in a project:

• If SBH_GRP is set to MIXED, the project may contain both steel and FRP objects. Every block is then defined to contain either steel or FRP, so the two may not be mixed within the same block.

• If SBH_GRP is set to any other value, the project may contain FRP objects only.

• If SBH_GRP is not set, the project may contain steel objects only.
