In pre-engineered building design, assumptions play a critical role in ensuring that structural analysis and design are both accurate and reliable. The Design Assumptions document highlights the key engineering considerations, methodologies, and simplifications applied when MkaPEB analyzes and designs single-storey steel structures.
MkaPEB goes beyond standard calculation routines by incorporating modern design practices, code-based checks, and advanced structural modeling techniques. The purpose is not only to calculate member forces and capacities, but also to make the underlying engineering logic understandable to the engineer.
1
Cold-formed membersPurlins and girts are treated with attention to stability, local buckling, overlap behavior, and practical support conditions.
2
Critical connection zonesOverlap regions, bracing points, expansion gaps, and other local zones are considered as part of the design interpretation.
3
Global and local stabilityBeam, column, and truss behavior can be affected by lateral-torsional, flexural, and flexural-torsional buckling modes.
4
Specialized systemsTension-only bracing and similar project-specific systems are addressed with attention to permitted applications under wind and seismic actions.
5
Geometry and limit statesSection variation, load eccentricity, member slenderness, and serviceability limits are part of the design logic.
By transparently presenting these assumptions, MkaPEB helps engineers understand how the software interprets structural behavior and how project-specific settings affect the final design. Users can rely on automated checks while retaining control over parameters that require engineering judgment.
