Plate Thermal Loading High end automatic mesh generation – draw a polygon with any number of sides to create a mesh of well formed quadrilateral (NO triangular) elements Accurate analysis of tapered wide flanges - web, top and bottom flanges may all taper independently Multiple simultaneous moving loads with standard AASHTO loads and custom moving loads for bridges, cranes, etc. Automatic Top of Member offset modeling Joint master-slave assignments |
Enforced joint displacements 1-Way members, for tension only bracing, slipping, etc 1-Way springs, for modeling soils and other effects Euler members: Compression up to buckling load, then turn off Story drift calculations provide relative drift and ratio to height Automatic self-weight calculations for members and plates Beam deflection ratio options. Masonry lintel analysis using FEA |
Design Features
|
