Digital Appendix of "Influence of High Strength Rebars on Seismic Safety of Concrete Frames"

Archived in this document are numerical models and post-processing scripts that were used in the paper “Influence of High Strength Rebars on Seismic Safety of Concrete Frames”. The zip file contains three sub-folders: (1) FiberModelValidation, (2) FrameOpenSeesModel, and (3) HingeModelCalibration.
The FiberModelValidation folder documents the OpenSees models and MATLAB scripts for computing the damage indice of longitudinal reinforcing bars in concrete members. For beam-column tests, the main script is “BeamColumn_Test.m” which could be run directly for the eight beam-column experiments discussed in the paper. For wall tests, the main script is “Wall_Test.m” which could be run directly for the four T-shape wall experiments.
The FrameOpenSeesModel folder documents the OpenSees model used for running incremental dynamic analyses for the archetype frames in the study. The two case-dependent modeling scripts are “bc_data_XXXXXXX.tcl” and “hinge_data_XXXXXXX.tcl”. The two scripts in the current main directory were created for the 20-story frame using Grade 60 bars (T/Y = 1.3 and s/db = 6). Other cases can be built with the corresponding scripts in the ModelingParameter folder.
The HingeModelCalibration folder documents the OpenSees models and MATLAB scripts for calibrating the cyclic deterioration parameter in the IMK hinge model. The two main scripts are “HingeModelCalibration_CPF_Test.m” and “HingeModelCalibration_PEER_SPD.m” which are separated only because their experimental data are in different unit systems. These two scripts could be run directly to run and compare IMK hinge-based simulations with the test results.
The relevant test data in this document were collected from previous studies including Berry et al. (2004), Huq et al. (2017), Sokoli et al. (2020), and To and Moehle (2020).
