Introduction
This examples demonstrates how to build a 3-story,3-bay frame. The nodes and elements are specified one by one.
Input
Model Building
The following tasks are performed when building the model
- define units
- define model
- define recorders for output
- define & apply gravity
Elastic Element
|
Distributed Plasticity Element, Uniaxial Section
|
Distributed Plasticity Element, Fiber Section
| ||||
Lateral-Load Analysis
The following tasks are performed in the analysis
- define lateral-load parameters
- analyze
Static
|
Dynamic EQ Ground Motion
|
Run
The model and analysis combinations for this example are numerous. The following are an small subset, for demonstration purposes:
- To run Elastic Mode, Static Pushover Analysis:
puts " -------------Elastic Model -------------" puts " -------------Static Pushover Analysis -------------" source Ex5.Frame2D.build.ElasticSection.tcl source Ex5.Frame2D.analyze.Static.Push.tcl
- To run Uniaxial Inelastic Section, Nonlinear Model, Uniform Earthquake Excitation
puts " -------------Uniaxial Inelastic Section, Nonlinear Model -------------" puts " -------------Uniform Earthquake Excitation -------------" source Ex5.Frame2D.build.InelasticSection.tcl source Ex5.Frame2D.analyze.Dynamic.EQ.Uniform.tcl
- To run Uniaxial Inelastic Material, Fiber Section, Nonlinear Model, Dynamic Bidirectional Earthquake Ground Motion
puts " -------------Uniaxial Inelastic Material, Fiber Section, Nonlinear Model -------------" puts " -------------Dynamic Bidirectional Earthquake Ground Motion -------------" source Ex5.Frame2D.build.InelasticFiberSection.tcl source Ex5.Frame2D.analyze.Dynamic.EQ.bidirect.tcl
