• define model, define & apply gravity

Elastic Section

• Elastic axial and flexural stiffnesses are defined at the section level, using a nonlinear beam-column element

• Ex5.Frame2D.build.ElasticSection.tcl

• LibUnits.tcl

• Build model – nodes, supports, elements, etc.
• elasticBeamColumn elements
• define & apply gravity load

Distributed Plasticity Element, Uniaxial Section

• Elastic axial and inelastic flexural moment-curvature properties are defined at the section level, using a nonlinear beam-column element

• Ex5.Frame2D.build.InelasticSection.tcl

• LibUnits.tcl

• Build model – nodes, supports, elements, etc.
• uniaxial inelastic section (moment-curvature)
• nonlinear beam-column elements

Distributed PlasticityElement, Fiber W-Section

• The section is broken down into fibers where uniaxial materials are defined independently. The program calculates flexural and axial stiffnesses/strength by integrating strains across the section.
