The concept of hybrid steel frame system is presented in which mixtures of fully-rigid and semi-rigid steel connections are used in the 3-, 9- and 20-story SAC frames. Several different patterns and locations of semi-rigid connection replacements within the frame are examined in…

Earthquakes affect millions of people across the earth. Earthquakes cause billions of dollars of damage and hundreds of thousands of deaths per year. For these reasons that seismic resilience is a field of immense concern for government, stakeholders and researchers. As the fiel…

Quantifying the seismic resilience of communities requires rigorous modeling of their behavior at disparate temporal (earthquakes – seconds vs. recovery – months) and spatial (component - meters vs. system - kilometers) scales. Hence, this dissertation has two main goals. The fi…

HSS are often used as bracing members in special concentrically braced frames (SCBFs) in areas of high seismicity. These systems efficiently resist seismic forces through the stable and ductile inelastic yielding and buckling of braces. However, the current requirements for brac…
