3D Structural Modelling & Analysis Examples

A few items are new in 3D:

 

  • nodal constraints (boundary conditions)
  • nodal masses
  • nodal loads

 

 

 

 

Objectives and Characteristics

Model Types

Analysis Types

Example 7. 3D Frame, 3-story, 3-bayX, 3-bayZ, Reinforced-Concrete Section & Steel W-Section

Embedded Power-Point Image

  • 3D frame of fixed geometry
  • nodes and elements are manually manually, one by one
  • introduce rigid floor diaphragm
  • use previously-defined procedures to view model node numbers and elements, deformed shape, and displacement history, in 3D
  • Reinforced-Concrete Section
  • Steel W-Section
  • Elastic or Fiber Section option is a variable within one input file
  • rigid diaphragm
  • static pushover analysis
  • static reversed cyclic analysis
  • dynamic sine-wave input analysis (uniform excitation)
  • dynamic earthquake-input analysis (uniform excitation)
  • dynamic sine-wave input analysis (multiple-support excitation)
  • dynamic earthquake-input analysis (multiple-support excitation)
  • dynamic bidirectional earthquake-input analysis (uniform excitation)

Example 8. generic 3D Frame, NStory NBayX, NBayZ, Reinforced-Concrete Section & Steel W-Section

Embedded Power-Point Image

  • 3D frame geometry of variable geometry ( # stories and # bays in X and Z are variables)
  • node and element definition is automated
  • introduce user-input interface, the user is given the option as to what to view in model
  • Reinforced-Concrete Section
  • Steel W-Section
  • Elastic or Fiber Section option is a variable within one input file optional rigid diaphragm
  • rigid diaphragm
  • static pushover analysis
  • static reversed cyclic analysis
  • dynamic sine-wave input analysis (uniform excitation)
  • dynamic earthquake-input analysis (uniform excitation)
  • dynamic sine-wave input analysis (multiple-support excitation)
  • dynamic earthquake-input analysis (multiple-support excitation)
  • dynamic bidirectional eaarthquake-input analysis (uniform excitation)
