OpenSees Example 2c. Nonlinear Cantilever Column: Inelastic Uniaxial Materials in Fiber Section
Introduction
In this example, the Uniaxial Section of Example 2b is replaced by a fiber section. Inelastic uniaxial materials are introduced in this example, which are assigned to each fiber, or patch of fibers, in the section.
Input
Static Pushover |
Dynamic EQ Ground Motion |
Run
- To run Static Pushover analysis:
- source Ex2c.Canti2D.InelasticFiberSection.Push.tcl
- To run EQ ground-motion analysis (BM68elc.acc needs to be downloaded into the same directory):
- source Ex2c.Canti2D.InelasticFiberSection.EQ.tcl
Notes
- In this example the axial and flexural behavior are coupled, a characteristic of the fiber section.
- The nonlinear/inelastic behavior of a fiber section is defined by the stress-strain response of the uniaxial materials used to define it.
