Reinforced Concrete Frame Example

This next example covers the nonlinear analysis of a reinforced concrete frame. The force based beam-column element with a fiber discretization is used in the model. The example is contained in three separate files:

1. RCFrameGravity.tcl - Defines the model and performs a gravity load analysis on the model
2. RCFramePushover.tcl - Subjects the portal frame of RCFrameGravity to a pushover analysis.
3. RCFrameUniformExcitation.tcl - Subjects the portal frame of RCFrameGravity to a uniform excitation.

In addition to the opensees modelling, these examples demonstrate Tcl language features such as variables, command substitution, expression evaluation, the if-then-else control structure, the use of procedures and the source command.
