Description

Exposed column base (XCB) model for OpenSees simulation 

Please read the documentation of the model 'XCB_model_documentation.pdf' before using the model.

1.  Generate_XCB.tcl and XCB_material.tcl

These are the subroutines that generate the XCB model

2. Two_Story_DissipativeXCB_MCE_LD_GM1.tcl

This is an example steel moment-resisting frame file in which the subroutines for XCBs are used

3. txt files

These are some output files (Story drift ratio history and column base moment - rotation responses) obtained from the frame file (Two_Story_DissipativeXCB_MCE_LD_GM1.tcl)  

4. The rest

These are the files required to run the frame file (Two_Story_DissipativeXCB_MCE_LD_GM1.tcl)
