Architectural Engineering: Graduate Reports
This project report summarizes the findings of a half-scale laboratory test on a slender lightly reinforced concrete (LRC) shear wall subjected to cyclic loading. LRC shear walls, specifically those of pre-1980’s type design, have longitudinal and horizontal reinforcement ratios near the code minimum, while often lacking confinement in the wall end-zones. These walls are thought to exhibit brittle compressive failure mechanisms such as rebar buckling or concrete crushing based on observations from past earthquakes. Non-ductile concrete buildings are a large contributor to earthquake losses around the globe, as noted in the San Fernando (1971) and Christchurch (2011) earthquakes, to name …

Architectural Engineering: Graduate Reports
A large number of pre-1980’s non-ductile reinforced concrete (RC) structures in California utilizing RC shear walls to resist seismic lateral forces have been identified as deficient by industry practitioners. These non-ductile wall systems are typically lightly reinforced and lack adequate boundary element detailing. Analytical studies suggest these walls are susceptible to brittle, compression-controlled failure modes due to damage from concrete crushing and bar buckling. Furthermore, poor behavior of lightly reinforced concrete walls was observed in many recent earthquakes, for example in Chile (1985), New Zealand (2010/2011) and Mexico (2017). This has generated concern among engineers in high seismic regions around …
