Using a range of comprehensive frame generation tools, MasterPort Plus enables you to model and design almost any portal frame structure in minutes.

3D steel frame generation tool

MasterPort Plus includes all the features of MasterPort, with the added benefits of full 3D modelling, automated wind loading and snow loading, along with advanced design group management.

Rapid Model Generation
  • Fast and easy portal frame modelling for multi bay, props, lean-tos, mezzanine floors, parapets, canopies and much more
  • 3D portal frame generation at the click of a button
  • Crane loading generation
Automated Load Application
  • Imposed, Dead & Services loads defined separately
  • Varying Mezzanine beam loading
  • UK & Irish sites can get accurate wind loading values. Define q for other regions.
  • Automatic Wind loading with full external and internal pressure co-efficients calculated
  • Automatic Wind loading on parapets, canopies & valleys calculated
  • Automatic internal volume calculation for internal pressures
  • Control of dominant openings on each building face
  • Automatic wind size reduction factors applied
  • Automatic Snow Loading, including drift cases
  • Intelligent design management of portal members, gable members, bracing components etc.
  • Automatic member sizing and positioning of purlins, side rails and torsional restraints
  • Buckling analysis calculation of in-plane elastic critical load factor
  • Eurocode 3 design using guidance from SCI P397 on member LTB
Optional Add-Ons

MasterCAD: BIM Integration

Generation of full portal frame General Arrangement drawings and 3D Model drawings in an instant. BIM integration with other software packages, like Revit, Tekla, and any other system which implements IFC specification.

MasterKey: Moment Connections
