Experimental Investigation of Seismic Resistant Construction Techniques

The study highlights the significant impact of masonry infill on the dynamic characteristics, stiffness, strength, and seismic performance of reinforced concrete frame buildings. The inclusion of infill walls enhances the building's stiffness and strength, effectively reducing inter-story drift and controlling lateral displacements, especially at the top stories. Key observations from the analysis reveal that the presence of infill results in a reduction in the fundamental period of the structure. Additionally, the displacement, particularly at the top story, is notably lower in buildings with infill compared to bare frames. Furthermore, the base shear increases with the inclusion of infill, with substantial variations observed between different models, especially under the dynamic response spectrum method. Finally, the study shows that story drift is significantly reduced in infilled frames compared to bare frames, leading to improved seismic performance and stability of the building.
