Static and P-Delta Analyses

• Linear, P-Delta analysis
• Multiple analysis in same run
• True curvilinear beams (not piecewise linear)
• Plate elements contain extra “drilling” degree of freedom
• Tapered tubular cross-sections such as hexagonal, octagonal, etc. (excellent for poles)
• Unidirectional support (compression-only/tension-only supports) for generation of soil springs
• Master/slave capabilities
• I-beam warping end restraint added as an option for torsional stiffness
• Buckling analysis
• Plate elements consider inclined supports
• Member and spring specification
• Fixed, pinned and spring supports with releases. Also Inclined Supports
• Automatic spring support generator for mat foundations
• Active/Inactive members for load-dependent structures
• Compression-only and tension-only members, multi-linear (non-linear) spring supports
• CIS/2 interface
• 3D beam stress manager for calculation of combined stresses on a member
• Member tension command can be used with IBC/UBC load generator
• Determine stresses and forces along any cut line through a group of plates by cutting with a plane
• Elbows (curved beams with pipe sections) can be modeled with an internal pressure
• Multi-linear spring curves can be assigned to elastic or plate mats
• Beam, truss, tapered beam, shell/plate bending/plane stress and 8-noded solid elements
• Full and partial moment releases (excellent for steeel frames where releases defined by springs are hard to determine)
• Nonlinear cable members for cables
• P-Delta analysis enabled for plates
• Imperfection analysis to account for cambering
• New automated bridge loader to calculate 3D influence surfaces, traffic lanes, critical vehicle loading positions, etc. (optional)
• Influence area reported for spring supports for elastic mats
• Warnings for “load losses” due to poorly defined beam releases
• Enhanced solid stress contour definition for brick elements
• Pushover analysis as per FEMA 356/440 codes with full visualization of formation of plastic hinges (optional)

Full buckling analysis to obtain buckling modes and factors for various loading conditions

Non-linear cable members to design catenary cables

Graphical and tabular representation of
singularities / instabilities to exactly pinpoint the area of the structure affected. Simplifies the process of correcting large deformations, incorrect moment and load transfers, etc.
