GS. Microstran and Multiframe File Conversion
The conversion tool can be used to convert Microstran and Multiframe files into STAAD.Pro files.
Microstran Files
The following obects are converted:
- Nodes
- Members
- Member Types
- Materials
- Sections Properties
- Releases and Offsets
- Supports
- Control-Dependent
- Load cases
- Load combinations
- Z-Up/X-Up/Y-Up - The Microstran model will be converted according to global axes convention in STAAD.Pro.
The following items are not converted:
- Analysis options
- Design
- Member type: gap and fuse are not supported
- Loading types not supported:
- Distributed (DIST)
- Trapezoidal moment (TRAP Moment)
- Triangular moment (TRI1 and TRI2 Moment)
Multiframe Files
The following objects are converted as described:
- Joints - converted to nodes
- Members including orientation (called beta angle in STAAD.Pro)
- End offsets - offset 1 are
start
local offsets and offset 2 areend
local offsets - Patches - converted to parametric models (including plate elements, nodes, and openings)
- Linked joints - converted to control-dependant node relationships, including degrees of freedom
- Restraints - including member releases
- Sections - those sections not mapped to standard database sections are converted to UPT or prismatic sections
- Materials - converted to isotropic material definitions
- Springs
- Load cases
- the self weight load case acceleration is converted to a self weight load case with corresponding factor
- Load items - member loads, joint loads, and patch loads should be categorized
separately
- Self weight
- Uniform loads
- Linear loads
- Concentrated loads
- Triangular loads and Tri-linear loads - converted to two or three trapezoidal loads, respectively
- Thermal loads
The following items are not converted:
- Spring members
- Load panels
- Patch edge releases
- Analysis options
- Design
