Parametric study of masonry-infilled RC frames with openings: subassembly contributions to shear resistance and the role of vertical confinement

Key Points

• Shear resistance is notably affected by subassembly contributions, enhancing overall stability in structures.
• Experimental findings indicate increased shear resistance by up to 30% when incorporating vertical confinement measures.
• Analysis of masonry-infilled frames identifies key parameters impacting structural integrity and performance.
• This analysis may enable refined design strategies for reinforced concrete frames in seismic-prone areas.
