Introduction

The following examples are listed in order of simplicity.

NOTE: gravity analysis is always included as part of the model building

Each example script does the following:

A. Build the model

  1. model dimensions and degrees-of-freedom
  2. nodal coordinates
  3. nodal constraints -- boundary conditions
  4. nodal masses
  5. elements and element connectivity
  6. recorders for output


B. Define & apply gravity load

  1. nodal or element load
  2. static-analysis parameters (tolerances & load increments)
  3. analyze
  4. hold gravity loads constant
  5. reset time to zero


C. Define and apply lateral load

  1. load pattern (nodal loads for static analysis, support ground motion for earthquake)
  2. lateral-analysis parameters (tolerances & displacement/time increments)
  3. damping for dynamic analysis
  4. analyze



Introductory Examples

The objective of Example 1a and Example 1b is to give an overview of input-file format in OpenSees using simple scripts. These scripts do not take advantage of the Tcl scripting capabilities shown in the later examples. However, they do provide starting a place where the input file is similar to that of more familiar Finite-Element Analysis software. Subsequent examples should be used as the basis for user input files.
