To understand the TCL code for the SCBF (Special Concentric Braced Frame) frame, you can refer to the following resources:
OpenSees TCL Example: The OpenSees TCL example titled "Special Concentric Braced Frame" provides a comprehensive overview of the TCL code for modeling and analyzing SCBF frames. You can find this example on the OpenSees website, which also includes a user manual and other helpful resources for using OpenSees.
NEHRP Seismic Design Technical Brief No. 7: The National Earthquake Hazards Reduction Program (NEHRP) has published a technical brief on the seismic design of steel SCBFs. This document provides a detailed description of the design and construction of SCBFs, as well as example calculations and design recommendations.
FEMA P-1050: The Federal Emergency Management Agency (FEMA) has published a document titled "Seismic Performance Assessment of Buildings" (FEMA P-1050). This document includes a section on the design and analysis of SCBFs, including example calculations and recommendations for modeling and analysis.
By studying these resources, you can gain a better understanding of the TCL code for SCBF frames, as well as the design and analysis principles that underlie their construction
