__NOTOC__
==Introduction==
Example 1b is a simple model of an elastic portal frame. The objective of this example is to give an overview of input format.

While the structural model is the same, there are three lateral-load cases:

==Run==
*To run Static Pushover analysis:
<blockquote><source lang="Tcl">
source Ex1b.Portal2D.Push.tcl
</source> </blockquote>

*To run EQ ground-motion analysis (BM68elc.acc needs to be downloaded into the same directory):
<blockquote><source lang="Tcl">
source Ex1b.Portal2D.EQ.tcl
</source> </blockquote>
