Study of Rampant slab for complex geometric element of Arch Profile

Abstract

Structural integrity in masonry construction has been a key focus of research for decades. Arches and vaults are fundamental elements in preserving this integrity, particularly in historical and monumental architecture. Since the 18th century, the evolution of domes and the integration of complex geometrical components such as masonry stairs and slabs have introduced significant structural challenges. Among these, the rampant arch plays a critical role in staircase stability, yet remains less standardized in architectural literature. This study investigates the structural behavior of rampant masonry arches, emphasizing the influence of arch profiles particularly segmental forms on load distribution and stress minimization. The analysis highlights the importance of profile geometry and masonry selection in optimizing compressive strength and ensuring performance under varying loads. These findings position rampant slabs as key elements in the advancement of sustainable and resilient architectural design.
