Abstract : This paper presents a comprehensive investigation of the structural analysis of unreinforced masonry (URM) and reinforced masonry (RM) structures, tracing the evolution from traditional construction techniques to modern engineering practices. Historically, the focus of structural design in ancient buildings was largely on geometry and material form. With the advent of steel and concrete, this focus shifted to the strength and resilience of materials. Utilizing both experimental data and computational modeling, this study compares the structural performance of URM and RM, highlighting the strengths and weaknesses of each method. The findings indicate that reinforced masonry structures exhibit superior strength and stability, making them more suitable for seismic regions, while unreinforced masonry can still be viable under specific conditions. The study concludes with recommendations for integrating traditional construction techniques with modern materials to enhance building safety and resilience.
