The building, as specified herein, consists of columns, rafters, bracing, connection clips, roof purlins, wall girts, roof and wall sheeting, anchor bolts, flashing, trims, etc., or as specified. All materials shall be new and free from defects.
1.
The main building structure comprises of single or multiple gable
interior rigid frames with either rigid or Ò post- and beam"
frames at the enwalls.
2.
The standard roof slopes are 0.5 or 1.0 unit of vertical rise to
10 units of horizontal run. Other slopes are available upon
request.
3.
The sidewall steel line is the plane of the inside vertical
surface of the sidewall sheeting. It is also the plane of the out
side vertical surface of the eave strut.
4.
The end wall steel line is the plane of the inside vertical
surface of the end wall sheeting. It is also the plane of the out
side vertical surface of the outer flange of the end wall girts.
5.
The building width is the distance between the steel lines of
opposite sidewalls. Building width does not include the width of
Lean-To buildings or roof extensions.
The width of a Lean-To building is the distance from the steel line of the exterior sidewall of the Lean-To building to the (sidewall or endwall) steel line of the main building to which the Lean-To building is attached.
6.
The building length is the distance between the steel lines
of opposite end walls. Building length is a combination of
several bay lengths. Building length does not include the width of endwall Lean-To buildings or roof extensions.
7.
End bay length is the distance from the outside of the outer
flange of endwall columns to the center line of the first interior
frame.
8
Interior bay length is the distance between the center lines
of two adjacent interior rigid frame columns.
9.
The building eave height is the distance from finished floor
level (FFL) to the top of the eave strut at the sidewall steel line.
10.
The building clear height is the distance from finished floor
level (FFL) to the bottom of the end plate of the rafter at the
knee.
(B) Standard Structural Framing Systems-
1.
Clear Span (CS) buildings have a gable roof with vertical
sidewalls and endwalls. Interior bay frames are clear span rigid
frames without interior columns.
2.
Multi-Span (MS) buildings have a gable roof with vertical
sidewalls and endwalls. Interior bay frames are rigid frames
typically having tapered exterior columns, tapered rafters
and square tube or built-up interior columns.
3.
Space Saver (SV) buildings have a gable roof with vertical
sidewalls and end walls. Interior bay frames are clear span
rafters typically with horizontal bottom flanges.
4.
Lean-To (LT) buildings consist of outer sidewall columns and
simple span rafters attached to the sidewall columns or the end wall posts of the main building. Lean-To columns are of constant depth. Lean-To rafters may be tapered or of constant depth.
5.
Multi-Gable (MG) buildings have a roof with two or more
gables and vertical sidewalls and end walls. Interior bay frames
are rigid frames typically having tapered exterior columns,
tapered rafters and built-up interior columns.
(C) Standard Framing Features-
1.
Main frames are typically constructed from tapered or constant
depth columns and rafters.
2.
Rigid frames for Clear Span (CS) and Multi-Span (MS) buildings
are most commonly spaced from 6000 mm to 10000 mm, center
line to center line.
3.
Outside flanges of Clear Span (CS) and Multi-Span (MS) rigid
frame columns are inset 200 mm from the sidewall steel line to
allow for by-pass girts.
4.
Outside flanges of Space Saver (SV) rigid frame columns shall be
placed flush with the sidewall steel line.
5.
1.3.5 The top flanges of all rigid frame rafters are 200 mm below
the bottom of the roof sheeting.
6.
End frames are Ò post-and-beam" (P&B) load bearing frames
with end wall girts flush framed into the webs of the end wall
posts so that the outer flanges of the girts are in the same vertical plane as the outer flanges of the posts. Optional rigid frames may be used at the building ends. The center line of the endwall rigid frame shall be 385 mm from the end wall steel line.
7.
Endwall posts are typically spaced at 6000 mm. Depending on
he width of the building and endwall openings, other spacing may also be used. When the building width is not evenly divisible by 6000 mm, the interior spacing of the endwall posts is typically
kept at 6000 mm with two equal end spacing smaller or larger
than 6000 mm.
8.
For Clear Span (CS) and Multi-Span (MS) buildings, the
dewall girts are attached (by-passed) to the outer flanges of
exterior columns. Sidewall girts are lapped at all interior frames.
For Space Saver (SV) and Lean-To (LT) buildings, the sidewall
girts are flush connected (flush framed) so that the outer flange
of the girt is in the same vertical plane as the outer flange of the
exterior columns.
9.
The bottom flanges of roof purlins are attached to the outer
(top) flanges of the rafters. Purlins are lapped at all interior
frames in all structural framing systems.
