Effects of Using High-Strength Reinforcement in the Seismic Performance of a Tall RC Shear Wall Building

Chile’s reinforced concrete (RC) design is based on ACI 318-08, where high-strength reinforcement not allowed in seismic force-resistant members. In 2019, new requirements adopted by 318 permitted the incorporation of walls. This study compared performance two Chilean 20-story residential buildings soft soil, one designed with traditional Grade 60 and other 80 reinforcement. The was assessed terms probability exceeding ASCE 41 limit states during a 50-year lifecycle. Analyses showed that both had similar performance. However, reduction building close to 18%. It concluded using typical wall implies significant used without affecting
