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 Files Ex2c.Canti2D.InelasticFiberSection.Push.tcl

Dynamic EQ Ground Motion Files Ex2c.Canti2D.InelasticFiberSection.EQ.tcl BM68elc.acc (ground-motion file)

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.
