Typical Specifications : Selectors and Pointers for Structural Components : Selectors

The following SELEC questions are those which you are likely to use when defining SPECs for structural components:

Defines the Specific Type of the component; particularly applicable to the general generic types PROF, JOIN and FITT. Examples of STYPE answers which might be applied to structural components to cover European, American and British standards include:


STYPE	Meaning
C	Channel section or American standard C–shapes (tapered flanges)
CHS	Circular hollow section
CRSJ	Castellated rolled steel joists
CUB	Castellated universal beams
CUC	Castellated universal columns
CZB	Castellated Z–beams
EAI	Imperial equal angles
EAM	Metric equal angles
HD	European columns (wide flanges)
HE	European beams (wide flanges)
HL/HX	European beams (very wide flanges)
HP	Bearing piles (wide flanges)
IPE	European beams (parallel faced flanges)
IPN	European standard beams (tapered flanges)
LST	Long stalk tee–bars
M/W	American I–shapes (wide flanges)
RHS	Rectangular hollow section
RSJ	Rolled steel joists
S	American standard I–shapes (tapered flanges)
T	Tee bars
TUB	Tees cut from universal beams
TUC	Tees cut from universal columns
U	European small channels
UB	Universal beams
UBP	Universal bearing piles
UC	Universal columns
UEAI	Imperial unequal angles
UEAM	Metric unequal angles
UPN	European standard channels
PLAT	Plate girders

The depth (height) of a structural section; e.g. 100 mm.

The width of a structural section; e.g. 100 mm.

The weight per unit length; e.g. 100 kg/m.

DIMEnsion integer:

Any dimension. The qualifying integer is optional; suggested conventions are:

Depth or long leg

Width or short leg

CTYPE integer

A connection type. The qualifying integer is optional; suggested conventions are:

Start connection

Attached connection

Owning connection

with the possible answers RIVET, BOLT, WELD, GLUE etc.

Start connection (equivalent to CTYPE1).

End connection (equivalent to CTYPE2).

Attached connection (equivalent to CTYPE3).

Owning connection (equivalent to CTYPE4).

INERtia integer

Moment of inertia about a specified axis; e.g. 280 cm$. (It is usually convenient to use cm rather than mm here to avoid having to list large values.) The qualifying integer is optional; suggested conventions are:

Inertia about x-x

Inertia about y-y

Inertia about u-u

Inertia about v-v

THICkness integer

Plate thickness within a section; e.g. 10 mm. The qualifying integer is optional; suggested conventions are:

Flange thickness

Joint fixity; e.g. FIXED, PINNED, PLASTIC, HINGED, RIGID etc.

Material grade for fire-resistant insulation; e.g. 43. (See Structural Insulation.)

Degree of fire resistance for insulation; e.g. 2 hr. (See Structural Insulation.)

Insulation thickness; e.g. 50 mm. (See Structural Insulation.)

Area of a section; e.g. 100 cm².

As for piping component specifications, you may also use any word, with or without a numeric qualifier, to define your own questions. See Selectors.
