The paper delves into the seismic performance of braced corrugated shear panels, examining the impact of varying thickness and depth of corrugations. Utilizing models with thickness ranging from 6 mm to 10 mm and depths of corrugations spanning 20 mm to 100 mm, nonlinear cyclic analyses are conducted under cyclic loading conditions. The results indicate that increasing thickness demonstrates substantial enhancements, with a 40% surge in energy dissipation capacity, a 20% rise in ultimate load resisting capacity, and a doubling of drift. However, deeper corrugations yield significant energy dissipation, and ultimate load increases up to a depth of 40 mm, beyond which a decline in energy dissipation capacity is noted. The study underscores the importance of optimizing thickness and depth configurations, with the findings revealing that simultaneous increase in both parameters may lead to panel overstiffening and diminished energy dissipation capacity. Overall, these insights provide valuable guidance for enhancing the seismic resilience of braced corrugated shear panels.
Braced Ductile Shear Panel (BDSP) represents a groundbreaking solution in the field of earthquake-resistant building design. It includes a rectangular ductile thin shear panel, concentric X-braces and a flange plate (Kelly et al., 1972). The thin shear panel is designed to leverage tension fields within the structure, improving ductility and lateral bearing capacity. By integrating these elements, BDSP aims to increase a building’s resistance to lateral loads and enhance its overall seismic performance.
