| The degree to which MBS processes building features is placed in two
categories:
PASS THROUGH:
Enter building input and the program fully processes all parts of the building
without additional effort by the user.
SEMI-PASS THROUGH:
Same as "Pass Through" only the user edits one or more input files and runs the
output files to obtain the complete output.
Examples with step-by-step instructions are provided for these cases.
In both these categories, there is no hand or electronic editing of the program
output generated by MBS.
The output can be printed or plotted without bringing it into AutoCADTMor similar programs.
I. Features used by MBMA to set Building Complexity
The complexity rating starts with a standard building.
Each higher complexity building includes additional building features. The
added building features along with the degree they are handled by MBS are
listed below.
Type 1 -
Standard Building
[Fully
Processed by MBS]
A Standard Building is a four (4) sided structure with all four sides solid
sheeted. It must have a standard load, width, and eave height. All doors,
windows, and accessories are to be field located. Standard Buildings can have
linear panels to the 7'4" girt at door head level. Lean-to's with solid
sheeting on three sides, attached to an existing structure, are also considered
standard. The above buildings can have expandable or non-expandable endwalls.
Type 2 -
Modified Standard Building
[Features
Fully Processed by MBS]
- Canopy at eave on sidewall only (one or both sidewalls)
- Two bay buildings
- Endwall roof overhang
- Standard building with standard lean-to attached
- Buildings partially open for masonry and glass
- Open endwall, supported by others; open rigid frame
endwall or open post and beam non-expandable endwall
- Linear panels - any non-standard height in walls
- Unbraced columns
- Alternating colors on walls
- Standard facades across one endwall and at least one
full bay down each sidewall
- Transverse partitions at frame lines
Type 4 & 5 -
Modified Building
[Features
Fully Processed by MBS]
- Combination of different standard bay lengths
- Canopy below eave height
- Special eave heights
- Portal frames or wind bents
- Flush concealed rafter canopy
- Standard building with crane
- One bay buildings
- Shop located accessories
- Standard building with special endwall bay spacing
- Transverse partitions away from frame lines and
longitudinal partitions
- Columnless endwalls with sheeted gables
Type 6 & 7 -
Special Buildings
[Features
Fully Processed by MBS]
- Special pitch - not shown as standard in price book and
engineering manual
- Non-standard bay spacings
- Special widths
- Drop in eave heights
- Unsymmetrical buildings
- Portal frames on buildings with canopies on same side
- Lean-to buildings with portal frames on same side
- Bays requiring bar joist for purlins
- Preparation of members for attachment of framework by
others
- Straight column rigid frame buildings
- Jack beams - Endwall lean-to's and/or endwall canopies
- Building governed by architect's specifications and/or
drawings
- Special slide doors
- Canopies with facade
- Canopies around corner
- Special height facades
- Facades on buildings with portal frames on same side
- Facades on either open endwalls or endwalls with
sheeted gables
- Parapet walls
- Hangar door endwalls
- Soldier Columns |
Type 8, 9 & 10 - Extra Special Buildings
[Features Fully Processed by MBS]
- Building requiring step columns for cranes
- Buildings with gambrel roofs
- Jack beams in the sidewall
- Bulk storage buildings
- Mezzanines supplied by manufacturer
[These
features are not on the current MBS schedule]
- Skewed walls
- Hip roofs
- Monitor, penthouse or clerestory
II. Additional Building Features Available in MBS
The MBMA building features used to measure building complexity are a starting
point in measuring software needs. As the building market changes, the software
needs to adapt to the market.
MBS "PASS THROUGH" FEATURES
- Multiple canopies at eave on sidewalls
- Open endwall, supported by others; open rigid frame
endwall or open post and beam non-expandable endwall
- Linear panels - any non-standard height in walls
- Multiple canopies below eave, on sidewall and endwall
- Standard building with crane
- Compression struts in roof
- Bolted connections for compression struts, eave struts,
and purlins
- Building cross sections with up to 14 surfaces
- Partial walls with a user selected member at the base
of wall
- Multiple levels of partial wall for each wall
- Each building can have up to 6 different rigid frames
- Each rigid frame can be unsymmetrical and have up to
20 unsymmetrically located columns and up to 60
member depths
- Endwall frames can be made from any combination of
these members: C section, double C section, hot rolled
wide flange, hot rolled C section, or welded plate wide
flange
- Detail and draw insulation with cut diagrams
- Design and fully detail standing seam roofs
MBS PROJECT
The term PROJECT is defined as more than one building combined as one building order. The user enters the quantity of buildings, the names of the buildings, the information common to all buildings, the information specific to each building, the location and rotation of each building, the intersection information, and the grid lines for the project. Snow loads caused by adjacent buildings are automatically generated by the program. Reactions from adjacent buildings are automatically transferred as loads to the adjacent building. The program automatically prepares design reports, detailing, and shop drawings for each building. It also prepares a combined shipping list, combined 3D drawing and erection drawings for the project building. |
