Below-Grade Structurla Flexibility Study For Seismic-Resistant, Self-Centering, Concentrically-Braced Frames, Derek A.J. Hauff
Williams Honors College, Honors Research Projects
Self-centering, concentrically braced frames (SC-CBFs) are seismic-resistant lateral-load resisting systems for buildings that increase the lateral drift capacity in comparison to conventional CBFs. Two different substructures were examined on a six-story and a ten-story building to see which below grade structure was more efficient and how the flexibility from the addition of a basement compares to previous research of SC-CBFs structures without basements.
The study was completed in phases: modeling of forces in SAP2000, sizing of structural members, coding of structure into the modeling program Open System for Earthquake Engineering Simulation (OpenSees), and comparison of the output data.
