- Package available for Australian, Canadian, and U.S. standards
- Simple tabular input
- Comprehensive and convenient tabular output of:
- Total concentrated loads applicable at panel boundaries
- Concentrated load per panel applied at panel centre
- Loads due to ladders
- Loads due to transmission lines
- Loads due to other mountings (appurtenances such as antennas, platforms, and ice guards)
- Individual element loads per unit length applicable to the materials specified in Material Types
- Loads due to antennas
- Integrated with other Guymast products to:
- provide loading data for GUYMAST®
- provide loading data for MASTTM
- provide graphical representations of the modeled tower using DRAWMASTTM
|
- Geometric description of towers using standard engineering terms and standard tower bracing types
- Panel oriented outline of mast geometry, allowing the description of large regions of the tower using a minimum amount of data
- The program can automatically model subdiagonals and subhorizontals (redundants) in order to obtain the proper wind and gravity loads
- Member properties are defined through reference to a list of materials prepared by the user
- Material properties such as cross-sectional area and unit weight are calculated by the program on the basis of shapes and sizes specified by the user. The shapes include:
- Solid Round
- Pipes
- Plates
- Angles
- Channels
- HSS
- Wide Flange & Tee Sections
- Pipe Schedules: STD, XS, XXS
- Any number of ladders of any size and composed of any of the materials listed in the Materials List may be specified for any region of the tower - position and orientation may also be specified
- Input and output units may be specified by the user as Imperial or Metric (SI). These may be different for input and output if the user wishes
- Any number of transmission lines (feeders) may be specified over any region of the tower, including position and orientation with respect to tower centre; a database of industry standard transmission lines is included
- Special appurtenances such as platforms, torsion resistors and antenna mountings may be specified at any location on the tower. Moment or torsion due to their eccentric location is automatically calculated
- Parabolic antennas and microwave horns may be specified at any elevation of the tower. Position and orientation may be specified individually
- Guy geometry information may be specified for guys at any elevation on the tower; a guy database is available which allows the user to incorporate material properties by reference to guy type (e.g. BS, GS & EHS) and diameter
- Up to 250 loading conditions may be calculated in each processing session
- Wind loading may be specified in terms of direction and speed or reference velocity pressure
- Wind variation with height may be according to a number of recognized industry standards, or as specified by the user with the input of exposure factors
- Ice loading may be specified in terms of radius of ice buildup and ice density
- Partial safety factors (LRFD) applicable to each loading condition may be specified
