Structural Modeling
 One physical member – one modeling object rule
 Automatic load cases, combinations and load placements
 Eccentricities – member, support, load – all the objects at their exact
position
 Complete connection integration – geometry identification, load
import
 Frame corner wizard

Structural Analysis
 The first design software using the 7 DOF finite element for the
global structural analysis
 Complete and accurate analysis of torsion and warping for any shape
 Complex second order analysis including all effects of eccentricities
 Direct calculation of all kinds of global and partial buckling modes
 Buckling mode based imperfections
 Dynamic analysis, response spectrum analysis
 Plastic hinge analysis: first order, second order, plastic buckling
 Shell finite element analysis: first order, second order, buckling, and
imperfections

Structural Design
 Fully automatic cross section checks based on EPS section model and
all types of design checks of EC3 for normal and fire situations
 Multilevel stability design:
 Fully automatic stability design based on the „General method” of EC3
 Buckling sensitivity calculation for members
 Member buckling checks based on the interaction methods of EC3
 Selected eigenvalue analysis for the accurate evaluation of effective
lengths and LTB of members
 Composite beam and column design based on GSS section model
 Fully integrated design of a wide range of structural connections
